Let the running time for movie b = x minutes
Running time for movie a = (x + 39) minutes
3x - (39 + x ) = 47 minutes
3x - x = 47 + 39 minutes
2x = 86 minutes, x = 43 minutes
So movie b runs 43 minutes
Movie a runs 43 + 39 = 82 minutes
Answer:
The surface area is 
Step-by-step explanation:
<u>Step 1: Determine the area of the bottom</u>
<u>Step 2: Determine the area of the triangles</u>
There are two of these right triangles on every side which means that we have 8 of these triangles so we multiply the area that we got by 8.
<u>Step 3: Combine the area to get the surface area</u>
Answer: The surface area is

Answer:
$7.20
Step-by-step explanation:
The first step is to convert 1 1/4 to decimal form. 1/4=0.25, which when added to the 1 gives a total weight of 1.25 pounds. Dividing this by the price to find the unit price, you get 9/1.25=$7.20 per pound of turkey. Hope this helps!
Step-by-step explanation:
By substitution is how to solve
2x-3y=21
y=3-x
2x-3(3-x)=21
2x-9+3x=21
5x=30
x= 6
now substitute our x value into y=3-x
so we get
y=3-6 = -3
so x=6 and y=-3 hope this helps!!!!! Thank you!
