Answer:

Step-by-step explanation:

Smallest Integer = 2x - 2

Middle integer = 2x

Largest integer = 2x + 2

All three are every

3(2x - 2) = 2(2x + 2)

6x - 6 = 4x + 4 Add 6 to both sides

6x = 4x + 6 + 4 Combine

6x = 4x + 10 Subtract 4x from both sides

6x-4x = 10 Combine

2x = 10 Divide by 2

x = 10/2

x = 5

2x - 2 = 2*5 - 2 = 8
2x = 10
2x+2 12

3*8 = 2*12

24 = 24

So the answers are correct.

In QPC, m∠C = (x + 11)°, m∠Q = (2x + 6)°, and m∠P = 70°.

olga55 [171]

Answer:

x=31

Step-by-step explanation:

QPC is a triangle. All angles of a triangle adds up to 180.

(x+11)+(2x+6)+70=180

x+11+2x+6+70=180

Combine like terms

3x+87=180

Subtract 87 from both sides

3x+87-87=180-87

3x=93

Divide both sides by 3

x=31
