Answer:
a. 4 teachers b. 58 students c. 62 people
Step-by-step explanation:
multiply 80 by 0.05, you get 4.
Multiply 1160 by 0.05, you get 58.
Add 80 and 1160 together, you get 1240. Multiply 1240 by 0.05, you get 62.
13/15
find the GCF = 4
52 / 4 = 13
60 / 4 = 15
X=22.5
Y=kX
20=15k
k=4/3
For X when Y=30
30=4/3×X
Cross multiply
4X=90
False. Perpendicular lines run beside each other not through each other.
