<h3>It'd be C. To find mean, you first add all the terms, than divide by how many terms there were. 12+8+7+10+8+8+10=63, and there are 7 terms, so 63÷7=9.</h3>

mean = 9 → C

mean = \frac{sum of data}{count}

         = \frac{12 + 8 + 7 + 10 +8 + 8 + 10}{7} = 9

Given: 3x + 1 = -14; Prove: x = -5
MrRissso [65]

Answer:

x = -5

Step-by-step explanation:

Solve for x:

3 x + 1 = -14

Subtract 1 from both sides:

3 x + (1 - 1) = -14 - 1

1 - 1 = 0:

3 x = -14 - 1

-14 - 1 = -15:

3 x = -15

Divide both sides of 3 x = -15 by 3:

(3 x)/3 = (-15)/3

3/3 = 1:

x = (-15)/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

Answer:  x = -5
