A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21

Answer:
2/25 is the Answer, as a decimal it is 0.08
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x + 1/50 = 1/10
Step 2: Subtract 1/50 from both sides.
x + 1/50 - 1/50 = 1/10 - 1/50
X = 2/25
Proof that it is the answer
0.02 + 0.08 = 0.1
0.02 is 1/50
0.08 is 2/25
0.1 is 1/10
Hope this helps!
3C + 5A = 115
C + A = 33
A = 33 - C
3C + 5(33-C) = 115
3C + 165 - 5C = 115
-2C = -50
C=25
25+A=33
A=8
C=25, A=8
Answer:
Correct group: fourth image
Surface area = 32 in2
Step-by-step explanation:
The dimensions required is 2 x 3 x 2, so in one dimension we need 2 cubes, in a second dimension we need 3 cubes, and in the third dimension we need 3 cubes.
In the first image, we have a 2 x 3 x 3 prism.
In the second image (to the right of the first one), we have a 2 x 4 x 1 prism.
In the third image (below the first one), we have a 3 x 4 x 1 prism.
In the fourth image, we have a 2 x 3 x 2 prism, so this is the correct option.
The surface area os this prism is 2*(2*2) + 2*(2*3) + 2*(2*3) = 8 + 12 + 12 = 32 in2
