Answer:
r = 8
Step-by-step explanation:
<u>→Distribute the 7 to (-3r + 16):</u>
-16r + 15 + 17 = 7(-3r + 16) - 5r
-16r + 15 + 17 = -21r + 112 - 5r
<u>→Add like terms:</u>
-16r + 32 = -26r + 112
<u>→Add 26r to both sides:</u>
10r + 32 = 112
<u>→Subtract 32 from both sides:</u>
10r = 80
<u>→Divide both sides by 10:</u>
r = 8
Answer:
A Response Variable (or dependent variable) is that variable whose variation depends on other variables In short, the response variable is the subject of change within an experiment, often as a result of differences in the explanatory variables.
Step-by-step explanation:
Step-by-step explanation:
Solving
3x + -6y = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6y' to each side of the equation.
3x + -6y + 6y = 42 + 6y
Combine like terms: -6y + 6y = 0
3x + 0 = 42 + 6y
3x = 42 + 6y
Divide each side by '3'.
x = 14 + 2y
Simplifying
x = 14 + 2y
