Answer:
Step-by-step explanation:
In order to solve this, we need to assume that the angles involving x are supplementary, and the angles involving y are complementary.
(7x -8) +(13x -32) = 180
20x -40 = 180 . . . . . . . . . collect terms
20x = 220 . . . . . . . . . add 40
x = 11 . . . . . . . . . . divide by 20

(10y +22) +(7y) = 90
17y = 68 . . . . . . . . . . . . collect terms, subtract 22
y = 4 . . . . . . . . . . divide by 17
300/4 ÷ 4/4 [Divide the numerator and denominator by 4] = 75%. Answer: 75% (ii) Express 12/5 as a percent. Solution: 12/5 × 100 = (12 × 100)/5 = 1200/5
Answer:
First one: 0.4
Second one: 4
Step-by-step explanation:
We find the cube root of 0.064 which is 0.4
In order to find the length of side s, we just cube root 64 because it is
