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
area = 277 units²
area = (25 x 5) + (8 x 13) + (8 x 6) = 277 units²
x=2
Isolate the variable by dividing each side by factors that don't contain the variable :)
