Bella has joined a new gym in town. The cost of membership is $25 per month. The after-hours policy at the gym allows her to wor

hjlf

The total monthly bill of the gym = $53

The cost of membership of a month = $25

Let 'n' be extra the number of hours Bella worked on.

The cost for working on extra hours = $4

So, we have to determine the equation, Bella worked out after hours.

We will determine the equation by:

(Monthly cost of membership) + ( cost for extra hours $\times$ number of hours extra worked on ) = Total monthly bill received

So, we get

$\$25+(4 \times n) = \$53$

$25+4n = $53 is the required equation.

Therefore, $25+4n = $53 equation can be used to determine how many times Bella worked out after hours.

for the first condition, i.e, she has decided to spend at most $150.00 on books,the required inequality will be :

$8x+12y\leq 150$

for the second condition , i.e, she wants to purchase at least 12 books,

If HJ= 7x-27 . Find the value of x

Alinara [238K]

we are given

$HJ=7x-27$

Since, we have to solve for x

so, we will isolate x on anyone side

step-1: Add both sides 27

$HJ+27=7x-27+27$

$HJ+27=7x$

step-2: Divide both sides by 7

$HJ+27=7x$

$\frac{HJ+27}{7}= \frac{7x}{7}$

now, we can simplify it

$\frac{HJ+27}{7}= x$

$x=\frac{HJ+27}{7}$ ................Answer
