So since you combine 12x + 5x you get 17x and then since 7 doesn't have a variable you don't combine it and even if it did it would have to have the same variable in order to combine.

So the answer would be
17x+7

12 and 5 have the same variable so u can add those two and get 17 and multiply the x which is 17x + 7 yea

Gabriel saves 40% of his monthly pay check for collage. He earned $270 last month. How much money did Gabriel save for collage

Ivan

Hi there!

I do not know the other values of the pay check, so I will explain to you how to solve for 40% of the 270 dollars. To solve, we'll need to set up a proportion. That proportion is 40/100 = x/270. Next, we need to cross-multiply: 100x = 10800. Lastly, we'll divide to figure out what 40% of 270 is. x = 108.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

A restaurant sold 35 burgers with cheese if the ratio of the burgers sold with cheese compared to without cheese was 7 : 3 how m

Montano1993 [528]

We need to write a proportion to solve this

7/3=35/x

105=7x

divide each side by 7

15=x so, there were 15 burgers without cheese.

We could add the cheese burgers 35 to burgers without cheese 15

35+15=50 burgers were sold.
