1) 9+4a-36+21-6a 2) -2a-6 3) -2a=6 4) a=-3
Answer:
1. 91 = 70*1.30
2a. 195= 150*1.30
2b. 210 = 150*1.40
3a. 56.70 = 156* .30
3b. 132.30 = 156-56.70
3c. 17.20 = 132.30 *0.13
3d. 149.50 = 132.30+17.20
3e. You do not have enough money, because you need $9.50 more.

answer:
6
step-by-step explanation:
- for this you would find the volume and then divide by 1/2
v = l x w x h
v = (1)(2)(3/2)
v = 3
3 ÷ 1/2 = 6
- therefore, it will take 6 half cubes to fill up the container
The answer is 126in^2. The formula for calculating trapezoid is A=a+b/2(h). Area=base 1+base 2 divided by 2 times height. Base 1 is 12in. Base 2 is 2in+2in+12in=16in. And the height is 9in. So 12in+16in=28in. 28in/2=14in. 14in(9in)=126in^2.
