Answer: x = 2/3
Answer:
a/ (5r^2) = t
Step-by-step explanation:
a= 5r^2 t
Divide each side by 5r^2
a/ 5r^2 = 5r^2 t/5r^2 t
a/ 5r^2 = t
Answer:
Answer: It can be written as 1.47x10-³
Step-by-step explanation:
0.00147 = 1.47
1.47 = 1.47 x 10 -^3
Consecutive odd or even integers are of the form x, x+2.
So we have x(x+2) = 63, where Diane's age = x.
x²+2x = 63.
x² + 2x - 63 = 0
(x + 9)(x - 7) = 0
x = -9, or 7.
Since -9 is awfully young, we rule it out and say Diane's age is 7, and her sister is 9.
