Answer:
z + 12 = 9
Reorder the terms:
12 + z = 9
Solving
12 + z = 9
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + z = 9 + -12
Combine like terms: 12 + -12 = 0
0 + z = 9 + -12
z = 9 + -12
Combine like terms: 9 + -12 = -3
z = -3
Simplifying
z = -3

Answer:
--273
Step-by-step explanation:
100th term is equal a1 + 99d so
100th term = 222 + (-5×99) = -273
Answer:
x = -2
Step-by-step explanation:
-6x - 29 = 5x - 7
Add -6x to both sides
-29 = 11x - 7
Add 7 on both sides
-22 = 11x
Divide
= 
x = -2
Answer:
9
Step-by-step explanation:
This is a right triangle. We can use the Pythagorean theorem to determine the missing side.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 12 ^2 = 15^2
a^2 +144 =225
a^2 = 225-144
a^2 = 81
Taking the square root of each side
a = 9
