Since you are subtracting 11 on the side with the variable, you have to add it on the other side. 17+11=28. Then, to solve the problem you are left with, 7c=28. You are multiplying on the side of the variable, so you divide 28 by 7. Your answer to the problem is C=4 i hope this helps

Inverse equation t=120r/r+120 R=???
Komok [63]

9514 1404 393

Answer:

  r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

  t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}

Answer:

100 Candy Bars

Step-by-step explanation:

Hey!

==================================================================

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

--------------------------------------------------------------------------------------------------------------

We can create an algebraic Equation to solve this.

<u>- We know that Each Candy Bar costs $1.50.</u>

<u>-We multiply the Amount of Candy Bars with the price. </u>

<u>-We know the profit should be $150</u>

⇒ 1.50x = 150

-<u>Divide</u> by 1.50 on both sides

⇒ 1.50x/1.50 = 150/1.50

-<u>Simplify</u>

⇒ x = 100

==================================================================

the product of 8 and a number , increased by 52, is equivalent to the product of 12 and the sum of the number and 2 . find the n
Step2247 [10]

8n+52=12(n+2)

distribute

8n+52 = 12n+24

subtract 8n from each side

52=4n +24

subtract 24 from each side

28 = 4n

divide by 4 on each side

7=n
