Students at a middle school were surveyed on how they get to school. Out of 230 students, 10% said they ride their bikes to school each day. 10% is equivalent to the unit fraction
.
To find 10% of 230, divide 230 by
.
10% of 230 is
.

10% is equivalent to the unit fraction 23

To find 10% of 230, multiply 230 by 0.10

10% of 230 is 23

Think about it, if 100% of 230 is 230, and 10% is 23, you can multiply 23 x 100 to get 230. I took a while to answer, but I hope my explanation helps.

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

now add them up : )
