Bree took another math test and scored 152 points, which was 85% of the total possible points on the test. What was the total number of possible points?

Step-by-step explanation:

Let's think this mathematically. Bree took a math test, and doing her best, she scored 152 points. And this 152 points was really 85% of the total possible points on this math test. Now we're like, huh, what IS the total number of possible points! Too bad we can't just go to Bree's math teacher and ask-

There are many ways to find the answer. Number lines, equations. This is what I did:

52 / 85 = 0.85

Now move the decimal point two times to get a percentage which gives you 85%. Or you can just get rid of the decimal point and put a 100 as a denominator. It's still the same thing.

Hope this helps! :D

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
