jada can write 3 1/4 pages in 8 minutes. At this rate, how many pages could jada write in 24 minutes?
makkiz [27]

Answer:

9  3/4  pages = x    

Step-by-step explanation:

\frac{pages}{minutes} = \frac{pages}{minutes}        change 3 1/4 to a decimal

\frac{3.25}{8} = \frac{x}{24}

3.25(24) = 8x

78 = 8x

\frac{78}{8} = x

9.75 = x  

9\frac{3}{4} =x

working with the fraction

3 1/4 /8 = x/ 24

3 1/4 (24) = 8x            

 13/4 (24) = 8x

  316/4 = 8x

  78 = 8x

78/8 = x

9 3/4 = x

Explain how you can use absolute value to tell whether
kicyunya [14]

Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

<u>Examples:</u>

  • 10 + 88 = 98
  • -20 + (-15) = -35

In case one of the integers is negative and one positive.

  • p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

<u>Examples:</u>

  • - 10 + 15 = |15 - 10| = |5| = 5
  • - 15 + 10 = - |15 - 10| = - |5| = -5

Find the mean, median, and mode 77, 92, 80, 92. Please explain how you got your answer.​
vaieri [72.5K]

Answer:

The mean is 85.25

The medium is 86

The mode is 92

Step-by-step explanation:

The mean is all the numbers added divided by the number of values.

77 + 92 + 80 + 92 divided by 4

341 divided by 4 = 85.25

The median is the middle number

92 + 80 divided by 2

172 divided by 2 = 86

The mode is the number that occurs the most which is 92.
