Answer:
Step-by-step explanation:
solve for x
note=anything you do on the other side of the equation you have to do inverse operation
-5x+10=-5
we have to move the ten on the -5 side so we do inverse operation
-5-10=-15
5x=-15
now we have to get the 5 by itself so what we do is inverse operation so we divide
-15/5
x=-3
In these problems, it is always a good idea to find the total population. In this case, it would be the total number of people who went on the field trip.
28+18+4=50
There are 50 people total.
To find each fraction, just put the number of students/parents/teachers over 50 and simplify.
Students
28/50=14/25
Parents
18/50=9/25
Teachers
4/50=2/25
Hope this helps!
Answer:
7 X 9 = 63
Step-by-step explanation:
Basically if 7 friends each spent $9 each you can times it to get the answer like 7x9 = 63 because each friend spent 9 each and there is seven so there for all together its 63
Let's start by calculating how many students does 24% represent.
24% * 24 = 0.24 * 24 = 5.76
We got a decimal number as solution. The reason why exactly 24% students can't be in the play is because this percentage does not represent whole number of students. She can't take 0.76 students
If she wanted 25% students to be in a play it would mean she has to take:
25% * 24 = 0.25 *24 = 6 students
