Answer:

The weight of each box must be less than 115 kg to be carried in the truck.

Step-by-step explanation:

The weight of the truck is, T = 875 kg.

Let the weight of one box be x kg.

Given:

[tex]875-4x>415[/tex] kg.

Solve the above inequality for x as follows:

[tex]875-4x>415\\-4x>415-875\\-4x>-460\\x<\frac{-460}{-4}\\ x<115[/tex]

As the weight of a box cannot be less than 0, the range of x is (0, 115).

Thus, the weight of each box must be less than 115 kg to be carried in the truck.

Part 1: The speed of the boat traveling downstream is [tex](18+w)[/tex] miles per hr.

The speed of the boat traveling upstream is [tex](18-w)[/tex] miles per hr.

Part 2: The speed of the current is 4 miles per hour.

Explanation:

Part (1): The motorboat travels 18 miles per hour in still.

Let w represents the speed of the current.

When the boat travels downstream, the speed of the current will get added to the speed of the boat.

Thus, the expression can be written as [tex](18+w)[/tex] miles per hr

Hence, the speed of the boat traveling downstream is [tex](18+w)[/tex] miles per hr.

When the boat travels upstream, the speed of the current will get subtracted to the speed of the boat.

Thus, the expression can be written as [tex](18-w)[/tex] miles per hr.

Hence, the speed of the boat traveling upstream is [tex](18-w)[/tex] miles per hr.

Part (2): The boat travels 49 miles upstream in the same time it takes to travel 77 miles downstream.

The distance formula is given by [tex]distance $=$ speed $\times$ time[/tex]

Substituting, we have,

[tex]49=(18-w)t\\49=18t-wt[/tex]  ---------------(1)

[tex]77=(18+w)t\\77=18t+wt[/tex]  ---------------(2)

Solving using elimination method,

[tex]49=18 t-w t\\77=18 t+w t\\-------\\126=36t[/tex]

Dividing both sides by 36, we have,

[tex]t=3.5[/tex]

Substituting [tex]t=3.5[/tex] in [tex]$49=18 t-w t$[/tex], we get,

[tex]49=18(3.5)-w (3.5)\\[/tex]

[tex]49=63-3.5w\\[/tex]

[tex]-14=-3.5w\\[/tex]

[tex]4=w[/tex]

Thus, the speed of the current is [tex]w=4[/tex] miles per hour.

Final answer:

The expression for the speed of the motorboat downstream is (18 + w) miles per hour. The expression for the speed of the motorboat upstream is (18 - w) miles per hour. To solve for the speed of the current, a system of equations can be set up and solved using the Elimination Method.

Explanation:

1. When the motorboat is traveling downstream (with the current), the speed of the motorboat will be the sum of its speed in still water and the speed of the river current. So the expression for the speed of the motorboat downstream is: (18 + w) miles per hour.

When the motorboat is traveling upstream (against the current), the speed of the motorboat will be the difference between its speed in still water and the speed of the river current. So the expression for the speed of the motorboat upstream is: (18 - w) miles per hour.

2. To find the speed of the current, we can set up a system of equations. Let t represent the time taken for both the upstream and downstream trips. The distance traveled upstream is 49 miles and the distance traveled downstream is 77 miles. Using the formula Distance = Speed x Time, we can write the following equations:

(18 + w) * t = 77

(18 - w) * t = 49

We can solve this system of equations using the Elimination Method. First, multiply the first equation by (18 - w), and multiply the second equation by (18 + w) to eliminate the variable w:

[(18 + w) * t] * (18 - w) = [(18 - w) * t] * (18 + w)

Simplify both sides of the equation:

(18 + w)(18 - w)t = (18 - w)(18 + w)t

Expand:

(18² - w²)t = (18² - w²)t

Cancel out the like terms:

324 - w² = 324 - w²

This equation is true for any value of w. Therefore, there are infinitely many possible values for the speed of the current w. The specific value of w would depend on the given values of t and the distance.

Answer:

x = 9

Step-by-step explanation:

x+3=2x-6

3=2x-x-6

9=x

The value of the x for the figure ABCD is 9.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of a polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

Given the quadrilateral ABCD and opposite sides are parallel,

AD ║ BC and AB ║ CD

since the opposite sides of the quadrilateral are parallel so the quadrilateral is a parallelogram,

so AB = CD

AB = x + 3 and CD = 2x - 6

x + 3 = 2x - 6

2x - x = 3 + 6

x = 9

Hence the value of x is 9.

Final answer:

Dexter rode an estimated 1.3 miles altogether after traveling 9/10 miles to the store and then 4/10 miles to his uncle's house.

Explanation:

You are asking how far Dexter rode his bike altogether after he traveled 9/10 miles from his house to the store and then 4/10 miles to his uncle's house. To estimate the total distance Dexter rode, we need to add the two distances together.

The sum of 9/10 miles and 4/10 miles is:

9/10 miles + 4/10 miles = 13/10 miles

To make it easier to understand, 13/10 miles can be converted to 1 3/10 miles, which is the same as 1.3 miles as an estimate, considering 10/10 equals 1 full mile. Therefore, Dexter rode an estimated 1.3 miles altogether.

Option c: (-6,1) is a solution for Line 2 only

Option d: (3,-1) is a solution to the system

Explanation:

Option a: (0,3) is a solution for Line 1 only

Line 1 is [tex]6 x-7 y=25[/tex]

Let us substitute the coordinate (0,3) in Line 1, we get,

[tex]\begin{array}{r}{6(0)-7(3)=25} \\{-21=25}\end{array}[/tex]

Since, both sides of the equation are not equal, the coordinate (0,3) cannot be a solution to Line 1.

Thus, Option a is not the correct answer.

Option b: (0,0) is a solution for Line 2 only.

Line 2 is [tex]2 x+9 y=-3[/tex]

Let us substitute the coordinate (0,0) in Line 2, we get,

[tex]\begin{array}{r}{2(0)+9(0)=-3} \\{0=-3}\end{array}[/tex]

Since, both sides of the equation are not equal, the coordinate (0,0) cannot be a solution to Line 2.

Thus, Option b is not the correct answer.

Option c: (-6,1) is a solution for line 2 only.

Line 2 is [tex]2 x+9 y=-3[/tex]

Let us substitute the coordinate (-6,1), in Line 2, we get,

[tex]\begin{array}{r}{2(-6)+9(1)=-3} \\{-12+9=-3} \\{-3=-3}\end{array}[/tex]

Since, both sides of the equation are equal, the coordinate (-6,1) is a solution for line 2 only.

Thus, Option c is the correct answer.

Option d: (3,-1) is a solution to the system

Let us substitute the coordinate (3,-1) in line 1 and line 2, we get,

In line 1, we have,

[tex]\begin{array}{r}{6(3)-7(-1)=25} \\{18+7=25} \\{25=25}\end{array}[/tex]

Substituting (3,-1) in line 2, we have,

[tex]\begin{array}{r}{2(3)+9(-1)=-3} \\{6-9=-3} \\{-3=-3}\end{array}[/tex]

Since, from line 1 and line 2, both sides of the equation are equal, the coordinate (3,-1) is a solution to the system.

Thus, Option d is the correct answer.

Option e: (3,1) is a solution to the system

Let us substitute the coordinate (3,1) in line 1 and line 2, we get,

In line 1, we have,

[tex]\begin{array}{r}{6(3)-7(1)=25} \\{18-7=25} \\{11=25}\end{array}[/tex]

Substituting (3,1) in line 2, we have,

[tex]\begin{array}{r}{2(3)+9(1)=-3} \\{6+9=-3} \\{15=-3}\end{array}[/tex]

Since, from line 1 and line 2, both sides of the equation are not equal, the coordinate (3,1) is a solution to the system.

Thus, Option e is not the correct answer.

Answer:

- 40, - 50, - 60

Step-by-step explanation:

Note the common difference d between consecutive terms of the sequence.

- 20 - (- 10) = - 20 + 10 = - 10

- 30 - (- 20) = - 30 + 20 = - 10

Thus the difference d = - 10

To obtain a term in the sequence subtract 10 from the previous term

- 30 - 10 = - 40

- 40 - 10 = - 50

- 50 - 10 = - 60

The next 3 terms are - 40, - 50, - 60

Let's begin with point A:

[tex]A(7,-4)[/tex]

So we need to find the coordinates of points D in order for ABCD to be a rectangle. So:

D can be found by reflecting A across the x axis:

So you just need to multiply the y-coordinate by -1, then:

[tex]D(x,y)=D(7,-1(-4))=D(7,4)[/tex]

Answer:

In 14 years Marc's grandmother will be 5 times as Marc will be then

Step-by-step explanation:

1. Information given to us to solve the problem:

Marc's age today = 0

Marc's grandmother age today = 56

2. In how many years will Marc's grandmother be 5 times as Marc will be then?

x = Number of years when Marc's grandmother age will be 5 times as Marc will be then

Let's solve for x, this way:

5 times Marc age in x years = Marc's grandmother age in x years

5 (0 + x) = 56 + x

5x = 56 + x

5x - x = 56 (Subtracting x at both sides)

4x = 56

x = 56/4

x = 14

Let's prove that x = 14 is correct:

5 (0 + 14) = 56 + 14

70 = 70

We proved that x = 14 is correct

In 14 years Marc's grandmother will be 5 times as Marc will be then
