Answer:
Ricky had 1199 hits.
Pedro had 1482 hits.
Step-by-step explanation:
State your variables
let "p" be the number of Pedro's base hits
let "r" be the number of Ricky's base hits
Create equations using information from the problem
p + r = 2681 [1]
p = r + 283 [2]
Substitute equation [2] in equation [1] replacing 'p'
p + r = 2681
r + 283 + r = 2681
Combine like terms to simplify
2r + 283 = 2681
Isolate '"r" to solve for Ricky's base hits.
2r + 283 - 283 = 2681 - 283 Subtract 283 on both sides
2r = 2398
2r/2 = 2398/2 Divide both sides by 2
r = 1199 Number of Ricky's hits
Substitute r = 1199 into any equation to find "p". I will use [2].
p = r + 283
p = 1199 + 283 Add
p = 1482 Number of Pedro's hits
Therefore Ricky had 1199 hits and Pedro had 1482 hits.
Ricky had 1199 hits and Pedro had 1482 hits.
Explanation:To solve this problem, we can set up a system of equations. Let x represent the number of hits Ricky had. Pedro had 283 more hits, so Pedro's number of hits would be x + 283.
Together, their hits add up to 2681, so we can write the equation:
x + (x + 283) = 2681
Combining like terms:
2x + 283 = 2681
Subtracting 283 from both sides:
2x = 2398
Dividing both sides by 2:
x = 1199
Ricky had 1199 hits and Pedro had x + 283 = 1199 + 283 = 1482 hits.

urgent please be my saint VX is a midsegment of △WYZ. If YZ=t+95 and VX=10t, what is the value of t?
Answer:
[tex]t = 5[/tex]
Step-by-step explanation:
By the mid-segment theorem of triangles,
[tex]VX= \frac{1}{2} YZ[/tex]
We substitute the expressions in terms of t.
[tex]10t = \frac{1}{2} (t + 95)[/tex]
We multiply through by 2 to get:
[tex]20t = t + 95[/tex]
Subtract t from both sides:
[tex]20t - t = 95[/tex]

Step-by-step explanation:
Multiply the diameter times 3.14
3.14 x 50=157 cm.
answer: 157 cm
To find the circumference of a circle given the diameter, multiply the diameter by π (approximately 3.14). Hence, the circumference of the dartboard is approximately 157 cm.
Explanation:The subject of the question is Mathematics and it covers a topic generally taught in Middle School. When given the diameter of a circle, you can calculate the circumference using the formula C=πd where C is the circumference, π (pi) is about 3.14, and d is the diameter. In this case, the diameter of the dartboard is 50 cm. So, we simply multiply the diameter (50 cm) by π (3.14) to get the circumference. This means the circumference of the dartboard is approximately

simplify the expression 6-2x+5+4x
Answer:
11 + 2x
Step-by-step explanation:
First you will want to separate like variables, so (6, 5) and then (-2x, 4x)
Then you will use the signs to do the math. You can move everything to help visualize the solution easier.
6+5+4x-2x
6+5 = 11
4x-2x = 2x
Because you cannot add or subtract a variable with a non variable, and both numbers are positive you end up with
11 + 2x
The expression 6-2x+5+4x simplifies to 11 + 2x by combining like terms: the constants (6+5=11) and the variables (-2x+4x=2x).
To simplify the expression 6-2x+5+4x, we start by combining like terms. Combining the constant terms (6 and 5) and the variable terms (-2x and 4x), we get:
Constant terms: 6 + 5 = 11
Variable terms: -2x + 4x = 2x
Thus, the simplified expression is 11 + 2x.

Marks car gets 30 miles per gallon for gas mileage. How many miles can Mark travel on 13 gallons of gas
Answer:
390 miles
Step-by-step explanation:
30 mpg means that he gets 30 miles for every gallon.
If he has 13 gallons means that you multiply 30 by 13.
30 * 13 = 390 miles
Final answer:
Mark can travel 390 miles on 13 gallons of gas, as his car gets 30 miles per gallon and distance is calculated by multiplying fuel efficiency by the number of gallons.
Explanation:
To calculate the distance Mark can travel on 13 gallons of gas, we use the formula: Distance = Fuel Efficiency imes Number of Gallons.
Mark's car gets 30 miles per gallon. Thus, the distance he can cover on 13 gallons of gas is calculated by multiplying 30 miles/gallon by 13 gallons, which equals 390 miles.
This is a straightforward multiplication problem involving units of fuel efficiency (miles per gallon) and quantity of fuel (gallons).
The solution directly gives us the total number of miles Mark can travel on 13 gallons of gas.
If inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year, what would you expect to pay for them this year?
Answer:
$76.5
Step-by-step explanation:
We have been given that inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year. We are asked to find the price of pair of designer jeans this year.
An inflation of 2% will increase the price of pair of jeans by 2%, so price of pair of jeans this year would be $75 plus 2% of $75.
[tex]\text{Price of pair of jeans this year}=\$75+\$75\times\frac{2}{100}[/tex]
[tex]\text{Price of pair of jeans this year}=\$75+\$75\times0.02[/tex]
[tex]\text{Price of pair of jeans this year}=\$75+\$1.5[/tex]
[tex]\text{Price of pair of jeans this year}=\$76.5[/tex]
Therefore, the price of pair of jeans would be $76.5 this year.

Write the expression "N is the same as 6 reduced by 2" as a number sentence.
Answer:
N = 6 - 2
Step-by-step explanation:
Take each part of the word expression and translate it:
"N" => N ("N" is a variable that represents a number you don't know)
"is the same as" => = ("the same" means equals)
"6 reduced by 2" => 6 - 2 ("reduced" means use subtraction "-")
Put the sentence back together in the same order.
N = 6 - 2
If you wanted to find "N", you can simplify by doing 6 - 2.
N = 4

Step-by-step explanation: The diagram shows a triangle which is actually in fact, two triangles placed into each other. The first one is triangle APR (the larger one) while the second one is triangle CDR (the smaller one).
Also the diagram shows line AP as being parallel to line CD. That makes triangle APR similar to triangle CDR.
We can now determine the ratios of the similar sides
If triangle APR = triangle CDR, then
Line PD/DR = AC/CR or
PD/PR = AC/AR or
CD/RD = AP/RP
Therefore to calculate X, we use the ratio,
PD/DR = AC/CR
15/42 = 10/x
{we reduce the left hand side to it's simplest form}

5x = 140
Divide both sides of the equation by 5
x = 28
one angle of a triangle has measure 26 degrees and another has measure 35 degrees. what is the measure, in degrees of the 3rd angle?
The measure of the third angle is 119 degrees
Step-by-step explanation:
The given is:
One angle of a triangle has measure 26 degreesAn another has measure 35 degreesWe need to find the measure of the third angle in the triangle
The sum of the measures of the interior angles of a triangle is 180°
∵ The measure of an angle = 26°
∵ The measure of another angle = 35°
∵ The some of measures of the 3 angles = 180°
∴ 26° + 35° + x° = 180°, where x is the measure of the 3rd angle
- Add the like terms in the left hand side
∴ 61° + x° = 180°
- Subtract 61 from both sides
∴ x = 119°
The measure of the third angle is 119 degrees

A concert hall has three sections: the main floor, the balcony, and the gallery. For a recent concert, 1020 tickets were sold. There were twice as many balcony tickets sold as gallery tickets, and 225 more main floor tickets than balcony tickets. If g represents the number of gallery tickets sold, which expressions represents this situation?
Answer:
Let the number of balcony seats be b
Let the number of gallery tickets be g
Let the number of main floor tickets be m
b + g + m = 1020
b = 2g
m = b + 225
The number of balcony tickets = 318
The number of gallery tickets = 159
The number of main floor tickets = 543
Step-by-step explanation:
Let the number of balcony seats be b
Let the number of gallery tickets be g
Let the number of main floor tickets be m
i) Therefore we can write b + g + m = 1020
ii) there were twice as many balcony tickets sold as gallery tickets
therefore b = 2g [tex]\Rightarrow[/tex] g = 0.5b
iii) there were 225 more main floor tickets than balcony tickets
therefore m = b + 225
iv) using equation ii) and equation iii) in equation i) we can write
b + g + m = b + 0.5b + b + 225 = 1020 [tex]\Rightarrow[/tex] 2.5b = 795 [tex]\Rightarrow[/tex] b = 318
v) g = 0.5 b = 0.5 [tex]\times[/tex] 318 = 159
vi) m = b + 225 = 318 + 225 = 543
Answer:
D. Gallery: g
Balcony: 2g
Main Floor: 2g+225
Step-by-step explanation:
Gallery is g
Balcony had 2 times as many tickets than Gallery so 2•g (2•gallery)
Main floor had 225 more tickets than Balcony so Balcony’s equation plus 225 tickets. 2g + 225
