Answer:
8.64. Her work is correct
Step-by-step explanation:
Given the expression to divide 2.16 by 0.25
Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;
2.16/0.25 = (2.16/0.01)÷(0.25/0.01)
(2.16/0.01)÷(0.25/0.01) = 216/25
216/25 = 8.64
Hence her value is 8.64 making her work correct
Supplementary angles are when both angles sum up to 180
So,
G is 20%*K, so convert to decimals hence,
0.20*k
Hence
0.20*K + K = 180 degrees
X=14. The angles are supplementary, meaning they both add up to 180, so you would subtract 96 from 180, getting 84. X + 5x = 6x, so you would divide 84 by 6 to get 14. Therefore, x=14.
