Hi there!

To solve this problem, we need to find the amount of classmates out of the entire class who did not choose blue as their favorite color and then convert it into a percentage. 

First, let's find the fraction:

Since there are 25 total people in her class, since

6 + 9 + 10 = 25

25 is the denominator of the fraction;

Since there are 16 people who did not choose blue,

6 + 10 = 16

16 is the numerator of the fraction. 

So, our fraction is 16/25. 

Now, we need to convert it into a percentage. To do this, we need to make the denominator 100 by multiplying it by a certain number, and then multiplying the numerator by that same number so the fraction stays equal:

16/25 
= 16*4/25*4
= 64/100
= 64%

So, the answer is 64% of Stephanie's classmates.

Hope this helps!

How do the expressions 72 divided and -72divided by (-9) and compare when they are evaluated?
padilas [110]

Complete question is;

How do the expressions 72 divided by 9 and -72 divided by (-9) compare when they are evaluated?

A. They have different values and are different signs.

B. They have different values but are the same sign.

C. They have the same value but are different signs.

D. They have the same value and the same sign

Answer:

D. They have the same value and the same sign

Step-by-step explanation:

For 72 divided by 9,it is;

72/9 = 8

Usually when we don't have any sign in front of a number, it is said to be positive.

Thus, the answer can be expressed as; +8

Also, when -72 is divided by (-9), it is;

-72/-9

The negative signs will cancel out to give; 8

Similar to the first division, since no sign is attached to 8,it is said to be positive as +8.

This means both divisions yield same values and same signs

let
x-----> </span>Susan's age
y---->  Steven's age

we know that
y+x=33-----> equation 1
3y-x/2=36----> multiply by 2----> 6y-x=72----> equation 2
adds equation 1 and equation 2

y+x=33
6y-x=72
-------------+
7y=105--------> y=15
x=33-y----> x=33-15----> x=18

the answer is
Susan's age is 18
Steven's age is 15
