Answer:29
Step-by-step explanation:
27r=783
divide both sides by 27
27r÷27=783÷27
r=29
X= 4.167 you cross multiply both the equations. so you get 30x - 50x = 10x - 125. you shift all the values of x on side and then divide it by 125 sso you get x= 4.167

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -5x - 2
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = -5(3) - 2
- Multiply: f(3) = -15 - 2
- Subtract: f(3) = -17
She accumulated an average rate of 12 CDs each year. You find this by subtracting 47 from 83 which gives you 36, dividing it by 3, which gives you 12.
