Answer:
x = -14
Step-by-step explanation:
Simplifying
7x + 156 = 9x + 184
Reorder the terms:
156 + 7x = 9x + 184
Reorder the terms:
156 + 7x = 184 + 9x
Solving
156 + 7x = 184 + 9x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9x' to each side of the equation.
156 + 7x + -9x = 184 + 9x + -9x
Combine like terms: 7x + -9x = -2x
156 + -2x = 184 + 9x + -9x
Combine like terms: 9x + -9x = 0
156 + -2x = 184 + 0
156 + -2x = 184
Add '-156' to each side of the equation.
156 + -156 + -2x = 184 + -156
Combine like terms: 156 + -156 = 0
0 + -2x = 184 + -156
-2x = 184 + -156
Combine like terms: 184 + -156 = 28
-2x = 28
Divide each side by '-2'.
x = -14
Simplifying
x = -14
To find the Mean or Average you have to add up all numbers it is asking for which in case are 222 and 198.
so you will add 222+198
That will equal 420
Then you will divide with the amount added together which is 2
420/2=210
so the mean of the 11 people is 210 or 210lbs

Answer:
y = -2/3x - 11/3
Step-by-step explanation:
Answer:
g(2) = 5
g(-2) = 2
g(-3) = 0
g(5) = 1
g(x) = 0 when x = 3
g(x) = 6 when x = 0
Step-by-step explanation:
Your just finding the values of y when x is unknown or when y is unknown and your trying to find x. f(x) is just a fancy way of saying y.
