http://prntscr.com/b1htwc Correct right? 10.50*x=147.00 = 14

OpenStudy (mathmale):

Without knowing the value of x, I can't say your result is "correct." What were the instructions for this problem?

OpenStudy (mathmale):

Note that * represents multiplication; is that what you meant? Note that if you want to specify exponentiation, you should use the symbol ^.

OpenStudy (mrnood):

147 does not equal 14 so please clarify the equation

OpenStudy (riff-raff):

10.50 * 14 = 147.00 So the answer is 14.

OpenStudy (mrnood):

correct

This problem might become easier for you to understand, and easier for potential helpers to understand, if you'd provide units of measurement. $10.50 is your "charge per lawn mowed." x is the number of lawns mowed. $147 represents your total earnings. Thus, your "\[\frac{ $10.50 }{ lawn}*(x~lawns) = $140.00\] " would be better expressed as

Thank you both for help

OpenStudy (mathmale):

Dividing $140.00 by ($10.50/lawn) will produce the correct answer, 14 lawns.

Caution: Don't use = twice as you have in this equation; 10.50*x=147.00 = 14 . what you are trying to say is that "the solution of 10.50x=147.00 is 14. Note how Mr. Nood told you "147 does not equal 14."
