25(2) + 7(1) + 3x = 78....x represents the number of 3 point shots
50 + 7 + 3x = 78
57 + 3x = 78
3x = 78 - 57
3x = 21
x = 21/3
x = 7....so there were 7 three-point shots made
The slope (9) is the amount of money you earn per hour, hence multiplying the amount by h, hours.

Step-by-step explanation:
Answer:
x + 43 = 72.98
<u> - 43 - 43</u>
x = 29.98
Step-by-step explanation:
Perimeter = sum of all the sides
let x = one side
longer side = x + 10
Perimeter = x + x + x + x + 10
62 = 4x + 10
4x = 52
x = 13
Longer side = 23
Area = (10+23)x2/10
= 6.6
