6 0

Answer:

You get 12$ per B and 15$ per A.  Thus, the answer is A) $282

Step-by-step explanation:

4A+4B=108

Divide by 4

A+B=27

Subtract B

A = 27 - B

3A+5B=105

Substitution

3(27-B)+5B = 105

Distribute

81-3B+5B=105

Combine like terms

81+2B=105

Subtract 81

2B=24

Divide by 2

B = 12

A = 15

14(15)+6(12)=x

210+72=x

282=x

Find the surface area of the rectangle prism. 3cm 9cm and 6cm
lisabon 2012 [21]

Answer:

198 cm²

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

        = 2(99)

       = 198 cm²

Therefore, the area of the rectangular prism is 198 cm²

9/2 as a mixed number
frutty [35]
In order to make \frac{9}{2} a mixed number you have to do division. \frac{9}{2}=4 \frac{1}{2}. Check:4 \frac{1}{2}= \frac{4*2+1}{2}= \frac{9}{2}. Therefore, \frac{9}{2} as a mixed number is \boxed{4 \frac{1}{2}}. Hoped I helped. :)
