Given that 2x – 2y = 23
lidiya [134]

Answer:

x = 41/2

Step-by-step explanation:

I am assuming that we are finding 'x' when y = 9.

2x-2y=23\\\\2x-2(9)=23\\\\2x-18=23\\\\2x-18+18=23+18\\\\2x=41\\\\\frac{2x=41}{2}\\\\\boxed{x=\frac{41}{2}}

Hope this helps!

Janiya has a shoebox with a volume of 609 cubic inches. The length of the shoebox is 14.5 inches and the width is 7 inches. What
devlian [24]

Answer:

6 inches

Step-by-step explanation:

Hi there!

V=lwh where l is the length, w is the width and h is the height of a rectangular prism

Plug in the volume (609), length (14.5) and width (7)

609=(14.5)(7)h\\609=(101.5)h

Divide both sides by 101.5 to isolate h

\frac{609}{101.5} =\frac{101.5h}{101.5} \\6=h

Therefore, the height of the shoebox is 6 inches.

I hope this helps!
