x < -23/2

Step-by-step explanation:

you open the bracket first

LHS

3-(2x - 5)

-6x+15

RHS

-4(x+2)

=-4x-8

therefore:

-6x+15 < -4x-8

By collecting the like terms

-6x+4x < -8-15

=-2x<-23

Divide both side by -2x

-2x/-2 < -23/-2

x < -23/2

10. Write a word problem for this equation:<br> n ($25) = $125
Andrei [34K]

Answer:

The word problem is "How many $25 are there in $125?"

<em></em>

Step-by-step explanation:

Given

n(\$25) = \$125

Required

Write a word problem for the expression

We start by solving the given equation

n(\$25) = \$125

Divide both sides by $25

\frac{n(\$25)}{\$25} = \frac{\$125}{\$25}

n = \frac{\$125}{\$25}

n = 5

This implies that there are 5, $25 in $125

<em>Hence; The word problem is "How many $25 are there in $125?"</em>
