1) Considering that there are 150 students
A) Adding 24+39 we got 63 students
150------------100%
63 ----------- x
x=6300/150
x= 42% of the students passed Math.
B) Adding the number of those students who live off-campus 39 +21
150 ----------------100%
60------------------ y
y=6000/150
y=40%
C) 60 students live off-campus 39 succeded. So we can write
60 --------- 100%
39 --------- z
z= 3900/60
z=65% passed math (off-campus)
D) Comparing that 65% of students who live off-campus passed math and that among those who live on campus and that 58% of all students failed
Then we can state:
A)
Answer:
96. (b)-0.066

Step-by-step explanation:
![| - 5x + 2| > 5 \\ - 5x > 5 - 2 \\ - 5x > 3 \\ x < - \frac{3}{5}](https://tex.z-dn.net/?f=%20%7C%20-%205x%20%2B%202%7C%20%20%3E%205%20%5C%5C%20%20-%205x%20%3E%205%20-%202%20%5C%5C%20%20-%205x%20%3E%203%20%5C%5C%20x%20%3C%20%20-%20%20%5Cfrac%7B3%7D%7B5%7D%20)
<h3>Hope it is helpful....</h3>
The percentage increase is 40%
If you multiply 45 by 1.4, you will get 63.
To solve, in a equation, it will look like this.
45x=63
And solve for x
I hope this helps.
YOU'RE WELCOME :D
