1 + 4 = 5, in this question, there is 1 "4", and 1 + 4 = 5
2 + 5 = 12, in this question, there are 2 "5", and 2 + 5 + 5 = 12
3 + 6 = 21, in this question, there are 3 "6", and 3 + 6 + 6 + 6 = 21
So for 5 + 8, there are 5 "8", so:
5 + 8 + 8 + 8 + 8 + 8 = 45
45 is your answer
hope this helps
vans = v, buses = b, students = s
8v + 8b =312s ...eqn 1
9v + 4b = 196s ...eqn 2
divide eqn 1 by 2
4v + 4b = 156s ...eqn 3
eqn 2 - eqn 3
5v = 40s
v = 8s
subst v = 8s in eqn 2
72s + 4b = 196 s
b = 31s
answer
each van holds 8 students and each bus holds 31 students
I used a triangle generator, see picture attached
Answer:
Yes it's A. 0.79
Step-by-step explanation:
You plug in 6.5 into the y-value since it asks to find the ratio,x, if the pHis 6.5. Then you can solve using a calculator to get 0.79432, or 0.79
