A cell phone plan charges $39.95 a month plus 15 cents per text message sent and 15 cents per text message received. Using s to
Allisa [31]

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)

Step-by-step explanation:

lesya [120]
<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

How are the angles of an equilateral triangle related?
julia-pushkina [17]
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
