Since Tracy can jump rope 26 times in a minute, we can make a equation.

  • 1\:minute=60\:seconds

Now here is our equation

\frac{26}{60} =\frac{x}{90}

cross-multiply

60x=2340

do simple algebra and divide

x=39

Tracy can jump rope 39 times in 90 seconds.

|6-27| how the answer this question
sweet [91]

Answer:

First notice that they’re asking for the absolute value of the equation.

The absolute value is how far that number is from 0.

Basically it’s the number without a negative sign.

ok so 6-27 = -21

The product for 6-27 (21) is 21 spaces away from 0.

|6-27| = 21

21 is the answer to your question.

Hope this helped and pls mark me brainliest if it did :)

Subtract .10 from both sides to get

Then divide both sides by .25
