Where was the 1st mistake made?
Given: 7 = 2(3x - 4)
Step 1: 2(3x - 4) = 7
Step 2: 6x - 6 = 7
Step 3: 6x = 13
Step 4: x =  $\frac{6}{13}$  

• Step 1

• step 2

• step 3

• step 4

Which step contains the 1st error? -2(x - 4) - 2 < 2

Step 1: -2x + 8 - 2 < 2

Step 2: -2x + 6 < 2

Step 3: -2x <-4

Step 4: x < 2

• Step 1

• step 2

• step 3

 $A=\pi r^2\ \ \ \ \ Solve\ for\ f$  

•  $r\ =\ \frac{A}{\pi}$  

•  $r\ =\ \sqrt{\frac{A}{\pi}}$  

• r =  $\frac{\pi}{A}$  

• r =  $\sqrt{\frac{\pi}{A}}$  

-2x + 3y = 15

• $y\ =\ \frac{-2}{3}x\ +\ 5$

• $y\ =\ \frac{2}{3}x\ +\ 5$

• $y\ =\ \frac{2}{3}x\ +15$

• $y\ =\ \frac{-2}{3}x\ +\ 15$

 $A=\frac{1}{3}\pi r^2h\ \ \ \ \ solve\ for\ h$  

•  $h\ =\ \frac{A}{3\pi r^2}$  

•  $h\ =\ \frac{A}{3\pi r}$  

•  $h\ =\ \frac{3A}{\pi r^2}$  

•  $h\ =\ \frac{3A}{\pi r}$  

Dexter's Gym charges a one-time registration fee of $40 and $20 each month. The total fee after x months is $340. Which equation models this situation?

• 40x + 20 = 340

• 20x + 40 = 340

• 20x - 40 = 340

• 20 + 340 = 40x
