c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.

This problem can be solved via a simple ratio and proportion approach. The concept is, the ratio of the actual length to the model length is constant. The solution is as follows:
Actual/Model = 12 m/ 1 cm = x/7.25 cm
Solve for x,
x = 87 m
<em>So, the actual distance is 87 m.</em>

Answer:
5x - 4 = 56
2x + 3 = 27
Step-by-step explanation:
2(5x - 4 + 2x + 3) = 166
10x - 8 + 4x + 6 = 166
14x - 2 = 166
+ 2 +2
14x = 168
divide both sides of the equal sign by 14
12
5(12) - 4 = 60 - 4 = 56
2(12) + 3 = 24 + 3 = 27
