<span>Solve thr proprtion for x. 14/20=17/x+12</span>cross multiply:
14 * x + 12 = 20 * 17
Simplifying14 * x + 12 = 20 * 17
Reorder the terms:14 * 12 + x = 20 * 1712 * 14 + x * 14 = 20 * 17168 + 14x = 20 * 17
Multiply 20 * 17168 + 14x = 340
Solving168 + 14x = 340
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-168' to each side of the equation.168 + -168 + 14x = 340 + -168
Combine like terms: 168 + -168 = 00 + 14x = 340 + -16814x = 340 + -168
Combine like terms: 340 + -168 = 17214x = 172
Divide each side by '14'.x = 12.28571429
Simplifyingx = 12.28571429

Answer:
a. 2x -3
b. 7
Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:
2(5) -3
= 10-3 = 7
