The answer is "D".
x+x+(x+11)+(x+11)=86
4x+22=86
subtract 22
4x=64
divide by 4
x=16
C.$47
Step-by-step explanation:
6% =0.06
0.06x50= 3
50-3= $47
The possible values of x are 3 and 7
<h3>Solving rational expressions</h3>
Given the rational expression below;
√60-8x = x - 9
Square both sides to have:
(60-8x)² = (x-9)²
60-8x = x²-18x+81
Equate to zero to have;
x²-18x+81 - 60 + 8x = 0
x² - 10x + 21 = 0
x² -3x-7x +21 = 0
x(x-3)-7(x-3) = 0
x = 3 and 7
Hence the possible values of x are 3 and 7
