Answer:
Option 4
Step-by-step explanation:
For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)
<u>#9-Step by step</u>
<u>Q=25</u><u>h</u>
divide 25 on both sides of the equation
Q/25=h
h=Q/25
Since his can't be simplified any further this is your answer
<u>#11.</u><u> </u><u>y=7m+6</u>
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
<u>#13 A=(Z+7)3</u>
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
<u>(</u>A/3)-7=Z
<u>#17. (2x/5)-9=6</u>
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2
x=75/2
x=37.5
