Does it say anything about slope?
Answer:
60 students passed, and 75 appeared in examination.
Step-by-step explanation:
Let's say s is the total number of students and p is the number of students who passed.
80% of the students passed, so:
0.8 s = p
If there were 10 less passers, and 15 less students (5 less failures), then the ratio of passers to failures would be 5/1.
(p − 10) / (s − p − 5) = 5 / 1
Simplify the second equation:
p − 10 = 5 (s − p − 5)
p − 10 = 5s − 5p − 25
6p = 5s − 15
Substitute the first equation.
6 (0.8 s) = 5s − 15
4.8 s = 5s − 15
0.2 s = 15
s = 75
p = 0.8 s
p = 60
60 students passed, and 75 appeared in examination.

okay i will dont sub to me
Step-by-step explanation:
can i have brainliest
Let us set up some variabe:
Use the known information:
Now lets find the area
Area = (1/2) * b *h = (1/2) * h * (2h + 8)
Hope that helps!
Answer:
11
Step-by-step explanation:
Step 1:
3/7r+5/8s
Step 2:
So u multiply 3/7 by 14
3/7 x 14= 42/7= 6
Step 2.5:
Now u multiply 5/8 by 8
5/8 x 8= 40/8= 5
Step 3:
<u><em>6+5=11</em></u>
