740-707.60=32.40
707.60-675.20=32.40
675.20-642.80=32.40
so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months

Answer:
0.6818
Step-by-step explanation:
3x+4=10
Subtract 4 from both sides
3x=6
Divide both sides by 3
X=2
Sides = 10,10,5
Problem 5. 4x+1=29
Subtract 1 from both sides
4x=28
X=7
the expression 
as a sum or difference is 
and , is simplified as 
.
<u>Step-by-step explanation:</u>
We need to rewrite the expression as a sum or difference , them simplify if possible , And the expression is :
From trigonometric identity we know that
Using the above identity we get:
⇒
⇒ 
⇒
⇒ 
⇒
Therefore , the expression as a sum or difference is and , is simplified as .
