Answer:
Step-by-step explanation:
<u>Given equation </u>
<u>To solve this for n divide both sides by 3.5:</u>
- 3.5n / 3.5 = 10.5 / 3.5
- n = 3
60% of 120 is 72. Therefore, Mark has only saved 72 dollars.
x and 4x are supplementary to each other, meaning they add up to 180. So your equation is 180=5x. Divide both sides by 5 to get 36=x.
Answer:
7
Step-by-step explanation:
x/ 8 = 3
x = 3 x 8 = 21
~~~~~~~~~
3x / 8 =
3(21) / 8 = 7
remainder = "7"
I dont know if this is wht u want .... but i hope its right !
