Evaluate each expression if x = 14 and y = 6

(x + y) ÷ 2 = _______

Evaluate 8a - b     if a = 10   and   b = 6

• 74
• 38
• 1000
• 9000

Evaluate the expression for a = 3, b = 4, c = 6

bc + 5a

• 99

• 39

• 63

• 87

What is the first step in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Multiply by 7
• Subtract 7

Solve for x:
8x - 10 = -34

• 4
• 3
• -3
• -24

Find the error in the problem below
19 - 2k = 3k - 1
     +3k   +3k
19 + 1k = -1
-19           -19
k = -20

• They should have divided by 1 for the last step
• They should add 19 instead of subtracting 19
• I can not find an error
• Instead of adding 3k they should subtract 3k
