What is the area of a rectangular holding pond with length 8/15 mile and width 1/6 mile?

SSSSS [86.1K]

as you already know, the area of a rectangle is just length*width, so is just the product of those two.

$\bf \cfrac{8}{15}\times \cfrac{1}{6}\implies \cfrac{8}{6}\times \cfrac{1}{15}\implies \cfrac{4}{3}\times \cfrac{1}{15}\implies \cfrac{4}{45}$

Solve the equation for y. 8x – 9y = 11

Vikentia [17]

8x - 9y = 11 (subtract 8x from each side)

- 9y = -8x + 11 (divide -9 from each side)

$\frac{-9y}{-9} = \frac{-8x+11}{-9}$

y = $\frac{-8}{-9} x - \frac{11}{9}$

D. $y=\frac{8}{9} x - \frac{11}{9}$
