-5y-6y is -11y=-22 so y=2
The elevator will be on the 76th floor in 60 seconds.
3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
Answer:
x = 9
Step-by-step explanation:
Assuming the rectangles are similar
13 x
------ = ---------
130 90
Using cross products
13*90 = 130*x
Divide each side by 130
13*90/130 = x
x = 9
