Answer:
w==77
Step-by-step explanation:
The sum of the 2 opposite interior angles equals the exterior angle.
w-36 +w-20=w+21
combine like terms: 2w-56=w+21
subtract w from both sides: w-56=21
add 56 to both sides: <u>w=77</u>
Answer:
the first one, 5(x-4) + 29
Step-by-step explanation:
(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6.
Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9
Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(:
Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!
