Suppose you spent $74.95 for a shirt and a jacket. The shirt cost $20.25. Solve the equation 20.25+j=74.95 to find how much you spent on the jacket.
You can work a simpler problem to estimate an answer. Use number sense to solve 20+j=75

So now do the same thing for your question. It's the exact same thing.

- anonymous

so it would be 74.95-20.25?

- anonymous

20.25 plus a number(\(j\)) equals 74.95.

- anonymous

"so it would be 74.95-20.25?"

when burned, 18 gallons of gasoline produce about 360 pounds of carbon dioxide. solve the equation 18n=360 to find how much carbon dioxide 1 gallon of gasoline produces.

- anonymous

you divide by 18 on both sides to get the answer

- anonymous

so wat is the answer?

- g152xx

20 I think.

- anonymous

can u show me how?

- g152xx

I can't now, i gotta leave. Sorry

- g152xx

there are plenty of people around who can show you in minutes.

- anonymous

i got you

- anonymous

360 = 18x if you divide by 18 you would get 20 because if 10 x 18 = 180 then 20 x 18 would be double that and 180 x 2 = 360
