heres why:
Let's solve your equation step-by-step.
4x−9(x+1)=20−5x
Step 1: Simplify both sides of the equation.
4x−9(x+1)=20−5x
4x+(−9)(x)+(−9)(1)=20+−5x(Distribute)
4x+−9x+−9=20+−5x
(4x+−9x)+(−9)=−5x+20(Combine Like Terms)
−5x+−9=−5x+20
−5x−9=−5x+20
Step 2: Add 5x to both sides.
−5x−9+5x=−5x+20+5x
−9=20
Step 3: Add 9 to both sides.
−9+9=20+9
0=29
so there are no solution

<u><em>Answer:</em></u>
Her hourly rate is $8.25
<u><em>Explanation:</em></u>
Tatianna works 3 hours a day on school days and makes a total of $123.75 in a week
<u>We know that:</u>
There are 5 school days in a week
<u>We are given that:</u>
She works for 3 hours a day each of those days
<u>Therefore:</u>
Total number of hours worked = hours worked daily * number of days
Total number of hours worked = 3 * 5 = 15 hours in a week
<u>The equation used to calculate Tatianna's earnings is:</u>
Amount she makes in a week = Total number of hours worked * hourly rate
<u>Now, we substitute with the givens to get the hourly rate as follows:</u>
Amount she makes in a week = Total number of hours worked * hourly rate
123.75 = 15 * hourly rate
Hourly rate = $8.25
