Let's assume
rent of the one chair = x
rent of the one table = y
3x + 2y = 24
8x + 4y = 53
multiply the first equation by 2
6x + 4y = 48
8x + 4y = 53
if we subtract from last equation to previous equation,
2x = 5
x = 2.5
y = 8.25
Therefore the cost of one chair is 2.5 dollars
the cost of one table is 8.25 dollars
Answer: 72 square inches
The first step is to convert all values into inches to apply the Area Formula. One foot=6 inches. Area: l*w so: 6*12 which is equal to 72 square inches.
Answer:
C(w) = 6w + 9
Step-by-step explanation:
Anytime 0 is given somewhere, it should be given close scrutiny. In an equation whose general form is
y = mx + b
0 will determine the y intercept immediately.
So when x = 0, y will equal
y = 0*m + 9
So b = 9
y = mx + 9 Now we need to find m
I should start using your variables.
C(w) = m*w + 9
when w = 3 then C(3) = 27
27= 3m +9
27-9 =3m + 9 -9
18 = 3m
18/3 = 3m/3
x = 6
So the complete equation is
C(w) = 6w + 9
The most likely answer is b
