Riverdale High ordered 84 shirts with their logo on them. if 8 of the shirts were defective what percent of the shirts were not
Ymorist [56]

8 were defective.

Defective percent = 8/84 x 100 = 9.5238% were defective.

Percent not defective = 100% - 9.5238% = 90.4761%

Rounding to the nearest tenth 90.5% were not defective.

The question doesn’t say how to round the answer so you may need to round differently than I did.

nexus9112 [7]
The answer is x=-20.
6+ -28 -x =-2
You first add 28 to each side=6+-x=26 then you minus 6 from each side=-x=20.
Then you divide 20 by -x resulting in x=-20

sesenic [268]

The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.

<h3>What is an expression?</h3>

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

<u>Given the following variables:</u>

  • m = 63.
  • n = 45.

Substituting the given variables into the given expression, we have;

Expression = (3m - n)² + 4m.

Expression = (3(63) - 45)² + 4(45).

Expression = (189 - 45)² + 180

Expression = 144² + 180

Expression = 20,736 + 180

Expression = 20,916.
