Ok do the original price minus the new price. 90-55=35. Divide that by the original number and multiply it by 100 to find the price decrease. 35/90=.3888*100=38.89

Formula #1: 0.15x + 22

Formula #2: 0.19x

0.15x + 22 = 0.19x

$15x+2200=19x\\15x=19x-2200\\-4x=-2200\\\frac{-4x}{-4}=\frac{-2200}{-4}\\X = 550$

So x = 550.

I hope this helps! :)

Drag steps in the given order to evaluate this<br> expression.<br> (-5)(2) – 2(-3) + 3

sesenic [268]

Answer:

-1

Step-by-step explanation:

using PEDMAS(parentheses, exponents, division, multiply, addition, subtraction) to solve the problem

First, multiply (-5)(2) and 2(-3)

(-5)(2) – 2(-3) + 3

=-10-(-6)+3

=-10+6+3

add -10+6

-4+3

Add -4+3

-4+3

=-1

Therefore, (-5)(2) – 2(-3) + 3 is equal to -1

A clothing truck is shaped like a rectangular prism. The volume of the truck 15 ft cubed. The area of the base of the container

Ghella [55]

Answer: 2.5 ft

Step-by-step explanation:

The volume of a rectangular prism is given by the following formula:

$V=(l)(w)(h)$ (1)

Where:

$l$ is the length of the base

$w$ is the width of the base

$h$ is the height of the prism

On the other hand, tha area of a rectangle is:

$A=(l)(w)$ (2)

Then, we can rewrite (1) in terms of (2):

$V=(A)(h)$ (3)

Now, we know the value of the volume and the area of the base:

$V=15ft^{3}$

$A=6ft^{2}$

Substituting these values in (3):

$15ft^{3}=(6ft^{2})(h)$ (4)

Isolating $h$ :

$h=2.5 ft$ This is the height of the truck
