It cost Faith $9.10 to send 91 text messages. How many text messages did she send if she spent $17.60?

um

Step-by-step explanation:

176 10cent per 1 message

176

Step-by-step explanation:

10 cents for 1 message because 9.10\91=.10 which is 10 cents

9.10=91 if you move the dot over once to the right you get your answer so...

17.60 mover to the right would be 176, .1 per text

-3

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
