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
Answer:
9x - 36 = 10
Step-by-step explanation:
3/4 x - 3 = 5/6
The least common multiple of 4 and 6 is 12.
Multiply both sides of the equation by 12.
12 * (3/4 x - 3) = 12 * 5/6
12 * 3/4 x - 12 * 3 = 10
9x - 36 = 10
First you write out your equation, which is 28x-42=154. Then you solve you equation. First, add 42 to each side, get 28x=196. Divide both sides by 28, get x=7.
25.1 yards
multiply the radius by 2 and multiply that number with pi and you get your answer of 25.1 yards
