Step-by-step explanation:

.19 = 19/100

.864 = 86.4/100

.5348 = 53.48 /100

I multiplied the decimal by 100 to get what it was before which is the same as moving two decimal places to the right and divided by 100

if any confusion ask

Here is your answer

$\bold{x=12}$

REASON:

$Concept used$ : The opposite sides of a parallelogram are equal.

So, in above given figure

$3x+7=5x-17$ (measures of opposite sides)

$5x-3x= 17+7$

$2x= 24$

$x= 24/2$

$x= 12$

22. A storage container is shaped like a rectangular prism. The volume of the container is1,360 cubic feet. The area of the base

Dovator [93]

The volume of the rectangular prism is

$V=B\times H$

Where:

B is the base area

H is the height

Since the base area is 160 feet^2

Since the volume is 1360 feet^3

Substitute them in the rule above

$\begin{gathered} 1360=160\times H \\ 1360=160H \end{gathered}$

Divide both sides by 160 to find H

$\begin{gathered} \frac{1360}{160}=\frac{160H}{160} \\ 8.5=H \end{gathered}$

The height of the container is 8.5 feet
