Answer:
There are 60 activity booklets in the media lab.
Step-by-step explanation:
- 30/2 = 15
Why divide those numbers?
For every 2 computers in a lab with 30 computers means you have to divide
- 15x4 = 60
Why multiply those numbers?
4 activity booklets for every 2 computers in a lab of 30 computers, so multiply
I hope this helps.
Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
So first we have to subtract 3y from 21 cause the oppisit of addition which is subtraction so you get 18y when we divide that with -8y and get y=2.25y
This is written in slope intercept form, or y=mx+b, where m is slope and b is y intercept. Just look at the values that represent m and b to find the answer.
Slope: 3/4
Y intercept: -4
