Answer:
17
Step-by-step explanation:
(7x)° + 61° = 180° (interior angle Postulate)
(7x)° = 180° - 61°
(7x)° =119°
7x = 119

Answer:
6u+7u-16=-81
We simplify the equation to the form, which is simple to understand
6u+7u-16=-81
We move all terms containing u to the left and all other terms to the right.
+6u+7u=-81+16
We simplify left and right side of the equation.
+13u=-65
We divide both sides of the equation by 13 to get u.
u=-5
Step-by-step explanation:

Answer: m = 5/8
Step-by-step explanation:
Isolate z by itself:

To simplify variables with powers, subtract the smaller power from the bigger power:


The exponent will be
-3.
