-8=p-13 how do you solve this problem
Answer:
you add -8 to 13
Step-by-step explanation:
-8+13=5
p=5
Answer: 5 = p
Step-by-step explanation: To solve the equation -8 = p - 13, notice that the variable is on the right side of the equation,
don't let this throw you off.
To solve for p, we need to get p by itself on the right side of the equation by adding 13 but if we add 13 to the right side of the equation, we also must add 13 to the left side of the equation.
On the right side of the equation, the -13 and + 13 cancel eachother out and we have p. On the left side of the equation, -8 + 13 is 5 so we have 5 = p which is the solution to our equation.
6x + 4y = 6
3x = -15
x = ____ y = ____
Answers:
x = -5
y = 9
============================================
Work Shown:
Start by solving the second equation for x.
3x = -15
3x/3 = -15/3 .... divide both sides by 3
x = -5
Then plug this into the first equation and isolate y.
6x + 4y = 6
6(-5) + 4y = 6 .... every x replaced with -5
-30 + 4y = 6
-30+4y+30 = 6+30 .... add 30 to both sides
4y = 36
4y/4 = 36/4 .... divide both sides by 4
y = 9

in a fundraiser, Mrs. Smith pledges $1 for each mile walked . if Sam walks 20 miles how much will Mrs. Smith donate? what is yhe constant proportionality of the problen
Final answer:
Mrs. Smith will donate $20 for Sam walking 20 miles, illustrating a direct proportional relationship with a constant of proportionality of $1 per mile, which is a simple yet effective example of how constants of proportionality function in everyday scenarios.
Explanation:
In the fundraiser mentioned, Mrs. Smith pledges $1 for each mile walked. If Sam walks 20 miles, Mrs. Smith will donate $20. The constant of proportionality in this problem is $1 per mile.
You can see this relationship as a simple formula: total donation = $1 × number of miles walked. So, if we replace "number of miles walked" with 20, the formula would be total donation = $1 × 20 = $20. This illustrates how the initial pledge creates a directly proportional relationship between the money donated and the miles walked.
The constant of proportionality here is crucial because it tells us how much money will be donated per mile that Sam walks. It is a straightforward example of how constants of proportionality work in real-life scenarios, similar to being paid for each call made in a phone drive or being charged per hour of tutoring.

Option A, 12/5
Step-by-step explanation:
If sin (theta) < 0 that means that the angle is in either quadrant 3 or 4.
Since cos or x is negative, that makes the angle limited to either 2 or 3.
The only quadrant that matches with those to is quadrant 3.
So, to find out what tan (theta) is, you need to make a graph and draw the line in quadrant 3.
Look at the attached graph
tan (theta) = opposite / adjacent
tan (theta) = -12/-5 = 12/5

Answer:
y = [tex]\frac{1}{2}[/tex] x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, - 5) and (x₂, y₂ ) = (- 4, - 4)
m = [tex]\frac{-4+5}{-4+6}[/tex] = [tex]\frac{1}{2}[/tex], thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 6, - 5), then
- 5 = - 3 + c ⇒ c = - 5 + 3 = - 2
y = [tex]\frac{1}{2}[/tex] x - 2 ← equation of line
To find the equation of the line through (-6, -5) and (-4, -4), calculate the slope and then apply the point-slope form to yield the line equation y = 1/2x - 2.
Explanation:The question is about finding the equation of the line that passes through two given points, (-6, -5) and (-4, -4). To do this, we first need to find the slope of the line (m) using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the points, we get m = (-4 + 5) / (-4 + 6) = 1 / 2. Next, we use the point-slope form of a linear equation, y - y1 = m(x - x1), to find the equation. Using point (-6, -5) and the slope 1/2, the equation becomes y + 5 = 1/2(x + 6). Finally, simplifying, we get y = 1/2x - 2 as the completed equation of the line.

B. 5π
C. 21.16
D. 4.6π
Final answer:
Wen Ti travels 9.2π feet in one complete spin on the outer edge of the carousel, which has a radius of 4.6ft. The correct option is A.
Explanation:
The question asks how far Wen Ti travels in one spin of the carousel, if she is on the outer edge with a radius of 4.6ft. To find this distance, we use the formula for the circumference of a circle, which is C = 2πr, where r is the radius of the circle. Plugging in the given radius of 4.6ft, we find that Wen Ti travels 2π(4.6) = 9.2π feet in one spin of the carousel.

Answer:
$68.60
Step-by-step explanation:

Machine a has a fixed daily cost of $40 and variable cost of one dollar per item produced. machine B has a fixed daily cost of $30 and a variable cost of $1.50 per item produced. A) what is the number of Items X for which the total daily cost C in dollars of each machine will be the same x items? B) what is the total daily cost per machine for this number of items?
To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up an equation and solve for x. The number of items x for which the total daily cost C of each machine will be the same is 20. For 20 items produced, the total daily cost per machine is $60.
Explanation:To find the number of items, x, for which the total daily cost, C, of each machine will be the same, we can set up the following equation:
40 + 1x = 30 + 1.5x
Simplifying, we get:
0.5x = 10
Dividing both sides by 0.5, we find:
x = 20
Therefore, the number of items x for which the total daily cost C of each machine will be the same is 20.
To find the total daily cost per machine for this number of items, we can substitute x = 20 into the equations for each machine:
Machine A: C = 40 + 1(20) = 60
Machine B: C = 30 + 1.5(20) = 60
So, for 20 items produced, the total daily cost per machine is $60.

2x - 3y = 45 and x + y = 10 what is the x - value of the solution of the system
Answer:
x=15
Step-by-step explanation:
This is a simultaneous equation
2x-3y=45 ------------------------------ equation i
x+y=10 -------------------------------equation ii
from equation ii
x+y=10
make x the subject of the matter
we have,
x=10-y

substitute x for 10-y
2x-3y=45----------------------i
since x=10-y
we have,
2(10-y) - 3y=45
20-2y=3y=45
collect like terms
-2y-3y=45-20
-5y=25
divide both sides by -5
we have y=-5
substitute y for-5 in equation i
x+y=10
x+-5=10
collect like terms
x=10+5
