The monthly cost of the cell phone plan, in function of the number of text messages sent(s) and the number of messages received(r), is given by:
In this question, we have that:
We put this into the equation to find the value of s. So
The total number of text messages sent was 27.
Answer:
Okay...
Step-by-step explanation:
You want to divide the cost of the books by the total costs.
308/2800 = 0.11

SOLUTION:
= 55° + 54° + x + 74°
= x + 183°
There is no answer to this expression.
Hence the correct answer is C) -23
Further explanation:
We have to put the values of m and n into both expression first separately and then multiply the answers.
Given expressions are:
The values are:
Putting the values in expression 1:
Putting the values of m and n in second expression
Multiplying both expressions:
Hence the correct answer is C) -23
