Answer:
c= 39.95 +0.15 (s + r) (take the 63 received and plug it in for r and 53.45 in for c then solve)
53.45= 39.95 +0.15 (s +63) (use the distributive property)
53.45 = 39.95 + 0.15s + 9.45 (combine like terms on the right side)
53.45 = 49.40 +0.15s (subtract 49.40 from both sides)
4.05 = 0.15s (divide both sides by 0.15 so isolate s)
s= 27 (how many text messages were sent)

<span>We simplify the equation to the form, which is simple to understand
<span>m/8-7=12
</span></span><span>Simplifying:
<span> + 0.125m-7=12
</span></span><span>We move all terms containing m to the left and all other terms to the right.
<span> + 0.125m=+12+7
We simplify left and right side of the equation.
<span> + 0.125m=+19
We divide both sides of the equation by 0.125 to get m.
<span>m=152
Hope this helps :)♥

The answer is 5.477225575.... or 5.5 if you want the simplified ansewer
There are 180 degrees in total inside a triangle.
If something is equilateral that means that all the angles are equal.
180/3 equals 60 degrees.
That means that all angles of an equilateral triangle are always equal to each other and if you must know, are 60 degrees
2x² + 5x -6x - 15 = 0
2x² - x - 15 = 0
2x² -x = 15
x = 3
3 x 3 = 9 x 2 = 18 - 3 = 15
i really don't know how i got 3 in the first place but that is your answer
hope this helps
