36 is 45% of 80
36/80 multiple both nominator and denominator by 100/100.
If using a calculator simply 36 divided by 80 and multiply by 100 giving you 45%
Suppose that the height (in centimeters) of a candle is a linear function of
the amount of time (in hours) it has been burning.
Let x be the amount of time in hours
Let y be the heoght of a candle in centimeters
The two points are then as (9,24.5) and (23,17.5).
Now plug in x=21, we get
Thus the height of the candle after 21 hours is 18.5 centimeters.
We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.
This sets up a problem of:
6x + 7 = 4x + 13
7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.
x = 3
Knowing this, we plug in x for one of the equations
6(3) + 7
18 + 7
25

Step-by-step explanation:
Let's examine the individual things
A. x=0 --> y=3.0-5=-5 True
B. x=-1 --> y=3.(-1)-5=-8 False
C. x=5/3 -->y=3(5/3)-5=0 True
D. x=2 --> y=3.2-5=1 True
Answer is B.
