Step-by-step explanation:
The given expression is:

We need to solve it to make q the subject of the formula.
Cross multiplying both sides,

Adding 3r to both sides,

Now, dividing both sides by r,

Hence, this is the required solution.
The first thing we are going to do to graph our equation is solve them for

:
For our first equation:



For our second equation:


Now, we just need to use the graphing utility to graph our equations:


We can conclude that the graph of the equations is:
Answer:
109.14
Step-by-step explanation:
to Start off do 60 x .70, then add the answer to 60, then multiply by .07 then add that to 102, for the answer of 109.14
16x + 40y.....GCF is 8
8(2x + 5y) <==
