Answer:
21
Step-by-step explanation:
84000/4000=84/4=21
Answer:
They are both equal!
Step-by-step explanation:
To find the answers, do the following
For 75% of 85 multiply 0.75 by 85:
(0.75)(85) = 63.75
For 85% of 75 multiply 0.85 by 75:
(0.85)(75) = 63.75
So, both of them are equal to each other.
HOWEVER, there is thing with percents that the opposites equal each other. So, you see how the percent and the whole number is changed with the equations? Like 85 turns to 85% and whatnot. If the percent/whole number of something is reversed it will equal the same thing.
So, you don't even need to do all the math to infer that they would be the same number. Changing the percent to the other number will yield the same result.
I hope that makes sense, ask questions if you need!!

Find x and 2x
From the attached image, we have:
--- vertical angles
Divide both sides by 2
Answer:
x=27
Step-by-step explanation:
distribute the 5 to the x and -4 then set both equations equal to each other subtract 4x from both sides add 20 to both sides and you're left with x=27
Answer:
y+7 = -3 ( x-4)
Step-by-step explanation:
First find two points on the graph to find the slope
( 1,2) and ( 3,-4)
The slope is given by
m = ( y2-y1)/(x2-x1)
m = ( -4-2)/(3-1)
= -6/2
=-3
We can use the point slope form
y - y1 = m(x-x1) where m is the slope and x1,y1 is a point on the line
We have two choices with a slope of -3
We can either use and x coordinate of -2 or 4
for -2, the y coordinate is not shown
for 4 , the y coordinate is -7
Using ( 4, -7) and m = -3
y--7 = -3( x- 4)
y+7 = -3 ( x-4)
