Explanation:
So, I know a lot of people won't do it this way, but this is how I would do it.
First, multiply each expense by eight (eight for the eight days)
$55 x 8 = 440
$25 x 8 = 200
$129 x 8 = 1032
Next, take the three answers and add them together:
440 + 200 + 1032 = 1672
Lastly, divide 1672 by four (four for the four friends)
1672/4 = 418
There you go! Here is your answer. Each friend paid $418
Hope I helped! :D
Remember this, DOOP
This stands for decimal, two zeros, then percent.
So, what you do is, since 1.513 is a decimal, you move the decimal two places to the right. You get 151.3
Therefore, 1.513 is 151.3%
Slope intercept form is y = mx + b...ur slope will be in the m position and ur y int will be in the b position
examples : slope = 2 , (1,3)....x = 1 and y = 3
y = mx + b
slope(m) = 2
(1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = 2(1) + b
3 = 2 + b
3 - 2 = b
1 = b
so in slope intercept form, ur equation is : y = 2x + 1
================
another example : slope = 3 , (-2,-4)
y = mx + b
slope(m) = 3
(-2,-4)...x = -2 and y = -4
now sub and find b, the y int
-4 = 3(-2) + b
-4 = - 6 + b
-4 + 6 = b
2 = b
so ur equation is : y = 3x + 2
Answer:
A
Step-by-step explanation:
State A has 25 drive-in movie screens and State B has 21. You find this by guess-and-checking different numbers that you could add together to get 46. You want to do numbers that are relatively close, as a difference in 4 is not much at all. You can divide 46 by 2 and then play around from there.
