3a + 2 - 5a = -14. Can someone solve this for me.

Answers

Answer:

a=8

Step-by-step explanation:

3a + 2 - 5a = -14

Combine like terms

-2a +2 = -14

Subtract 2 from each side

-2a +2-2 = -14-2

-2a = -16

Divide each side by -2

-2a/-2 = -16/-2

a = 8

Answer:

a = 8

Step-by-step explanation:

-2a + 2 = -14

-2a = -16

-16/-2 = 8

a = 8

Clint bought 3 T-shirts at $9 each and 2 pairs of shorts at $12 each. Explain how to find the total Clint spent.

Answers

total cost=shirtcost+shortscost

shirtcost=number of shirts time cost per shirt
shirtcost=3 times 9=$27

shortscost=number of shirts times cost per short
shortcost=2 times 12=$24

total cost=27+24=51

total is $51
You need to use multiplication.

3 x 9 = 27

2 x 12 = 24

Now add 24 and 27 wich make 51.

What is the surface area of the prism?A. 82 yd.^2
B. 90 yd.^2
C. 96 yd.^2
D. 108 yd. ^2

Answers

Surface area of the prism= surface area of the base + surface area of the two triangles + surface area of the two rectangles.

Surface area of the base=(3 yd * 7 yd)=21 yd².
Surface area of the two triangles=2*(3 yd * 4 yd)/2=12 yd².
Surface area of the two rectangles=(7 yd * 5 yd) + (7 yd * 4yd)=35 yd² + 28 yd²=
=63 yd²

Surface of the prism=21 yd² + 12 yd² + 63 yd²=96 yd²

Remember:
surface area of a triangle=(base * height)/2
surface area of a rectangle=base *  height.

Answer: C.96 yd²

Answer:

C.96 yd²
