This can get confusing. Sorry if it doesn’t make a lot of sense. I will explain #3

1) You first have to look at the equation. It says 100 acres to 140 acres. From that information you should know that the number increases, so the percent will be over 100.
2)to set the equation up you do
X
__ =
100
Since every percent is out of 100.
3) Now you have to put the numbers in the equation. Since the original number is 15, so you would put it on the bottom and 18 on top.
X 18
__ = __
100 15
Then you times across
15x=1800
To find x (the percent) you divide both sides by 15
15x 1800
__ = __
15 15
X=120%
It would be increased

How do you round 1.038 to the nearest hundredth

Talja [164]

You have to go past the decimal point in since the first number in the tenths place is a zero you can't really round here so you go to the hundreds place and not so three you round down because 3 is closer to 0 then it is 10 so it would be 1. 4

What is the equation of the line

kupik [55]

Answer:

y=-x+3.

Step-by-step explanation:

The graph goes down one and right one before making another point. This means that the slope is -1/1. Simplify and you get -1. So far we have y=-1x. -1x is the same as -1. Now we have y=-x. The graph intersects the y-axis at the point (0,3). This makes our y-intercept 3. Our final equation is y=-x+3.
