We must remember that average is simply the sum of all the scores divided by the number of scores. So:

165 = (157 + 161 + X) / 3

Calculating for the score of the third bowler X:

318 + X = 495

X = 177

 

Therefore the score of the third bowler must be 177 or greater. Hence:

<span>X ≥ 177</span>

Cheryl paid $37.20 for 12 gallons of ice cream for a school picnic. How much would 1 quart of ice cream cost?
Stells [14]
First, you need to get to one gallon, which is 37.20 divided by 12. (3.1)
Divide that number by four, which is: 0.775, or 0.78 rounded up to the nearest hundredth.
Hope that helped.

Riley just opened a checking account at the bank. Within the first month, she deposited three checks for $34.98, $51.02, and $51
FromTheMoon [43]

Answer:

34.98+51.02+51.22= 137.22 as a positive number. 5.23+10.22+7.89= 23.34 Then 137.22-23.34= 113.88

So the negative number will be -23.34
