Answer:
17. w = 15 18. S = 115°
Step-by-step explanation:
17. 10 · 6 = 4w
combine like terms:
=> 60 = 4w
divided by 4 on both sides:
=> w = 15
18. 180° - S = 65°
subtract 180° on both sides:
=> -S = -115° => S = 115°
17) 10•6 = 4w
Multiply:
60 = 4w
Divide:
60/4 = 4w/4
15 = w ———————————
18) 180° - S = 65°
Isolate the variable (subtract 180° on both sides):
-S = -115
You can’t have a negative angle so you divide -1 on both sides:
S = 115 ———————————
