The question is asking for 1/3 of Molly’s length, which is 20 inches. The word of in this context indicates multiplication, which means you should multiply 20 by 1/3.
1/3 x 20 = 6.666666 (repeating) or 6.7 (rounded)
Therefore, Molly is 6.7 inches tall.
3y= 5x-2
so the slope is 5/3
∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
4 times 1 = 4 so the top one would be 4/12, but i can't help with the rest because i don't understand what they are asking for
