To solve this, you need to isolate/get the variable "r" by itself in the equation:

-2(6 - r) = 4 Divide -2 on both sides

$\frac{-2(6-r)}{-2} =\frac{4}{-2}$

6 - r = -2 Subtract 6 on both sides

6 - 6 - r = -2 - 6

-r = -8 Divide -1 on both sides to get "r" by itself

$\frac{-r}{-1}=\frac{-8}{-1}$ (two negative signs cancel each other out and become positive)

r = 8

PROOF

-2(6 - r) = 4 Substitute/plug in 8 into "r"

-2(6 - 8) = 4

-2(-2) = 4

4 = 4

What expression is equivalent to -x + 5 - 13 + 12x

zvonat [6]

Answer:

11x - 8

Step-by-step explanation:

If you have x- + 5 - 13 + 12x, all we are doing is combining like terms. First, 5 - 13 = -8. Then, -x + 12x is the same as doing 12x - x. That gives us 11x. The answer would be 11x - 8 when you put -8 and 11x together in the expression.

The statement that "the margin of error was given as $\pm5$ percentage points" means that the population proportion is estimated to be with a certain level of confidence, within the interval $\hat{p} \pm 0.05$ ; where $\hat{p}[tex] is the sample's proportion. The correct answer is C. The statement indicates that the interval [tex]0.14\pm0.05$ is likely to contain the true population percentage of people that prefer chocolate pie.
