Plug 10 in for m
-16 = 10/5 - 18
-16 = 2 - 18
-16 = -16
Answer: The cost of renting a chair is $2.5 while the cost of renting a table is $6
Step-by-step explanation: Let the cost chair rental be called h, while the cost of table rental shall be called t. To rent two chairs and five tables cost $35, so we can express this as
2h + 5t = 35
Also to rent eight chairs and three tables cost $38, and this too can be expressed as
8h + 3t = 38
We now have a pair of simultaneous equations as follows
2h + 5t = 35 ———(1)
8h + 3t = 38 ———(2)
We shall use the elimination method since all the unknown variables have coefficients greater than 1.
Multiply equation (1) by 8 and multiply equation (2) by 2. We now have
16h + 40t = 280 ———(3)
16h + 6t = 76 ———(4)
Subtract equation (4) from (3)
34t = 204
Divide both sides of the equation by 34
t = 6
Having calculated that, substitute for the value of t into equation (1)
2h + 5(6) = 35
2h + 30 = 35
Subtract 30 from both sides of the equation 2h = 5
Divide both sides of the equation by 2
h = 5/2 or (2.5)
Therefore the cost of rental for each chair (h) is $2.5 and the cost of rental for each table (t) is $6
Area of a square is one side squared.
So x+5 ^2 is x^2 + 10x + 25

Answer:
Some ages that Mark could possibly be are...
16, 17, 18, 19, and 20. I found my answers because to have a job or work at a program, you have to be at <em>least</em> 16. So Mark could be 16, 17, 18, 19, or 20. He would be able to work being 21 because that is the drinking age and you are already in the adult stage and you are old enough to be responsible with what you do.
