smartboy23 3 years ago 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

1. geoffb

They've given you the formula. You just need to solve for \(j\).

If I told you 4 plus a number equals 9, how would you figure out what "the number" is? Tell me your process.

4. smartboy23

9-4

5. smartboy23

??

6. geoffb

Exactly! Good.

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

9. smartboy23

so it would be 74.95-20.25?

10. geoffb

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

11. geoffb

"so it would be 74.95-20.25?" Yes, it would. Good job. :)

12. g152xx

Yes.

ok

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.

34. Spectrum

you divide by 18 on both sides to get the answer

35. smartboy23

36. g152xx

20 I think.

37. smartboy23

can u show me how?

38. g152xx

I can't now, i gotta leave. Sorry

39. g152xx

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

40. Spectrum

i got you

41. Spectrum

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
