they all split it and is each going to have 6 dollars each plus the extra 2 for cleaning so 8 dollars each.
Answer - $8 Dollars
Answer:
-13,1
Step-by-step explanation:
f(x)= (x+6)^2-49
When we find the zero's we set f(x) =0
0= (x+6)^2-49
Add 49 to each side
49= (x+6)^2-49+49
49= (x+6)^2
Take the square root of each side
±sqrt(49) = sqrt((x+6)^2)
±7 = (x+6)
Subtract 6 from each side
±7-6 = (x+6-6)
±7-6 = x
7-6 =x -7-6 =x
1=x -13=x
6 rows with 6 chairs in each is 36 chairs bc 6x6=36
Hope this helps
In order to find the sale you divide the second price by the first price.
68/85 = .80
Answer: 80%
Answer:
Step-by-step explanation:
x*y = 490
x + y = 49
x = 49 - y
y*(49 - y ) = 490
49y - y^2 = 490
0 = y^2 - 49y + 490
This does factor (oddly). It doesn't look like it, but it does.
(y - 35) (y - 14) = 0
y - 35 = 0
y = 35
y - 14 = 0
y = 14
x = 49 - y
Let y = 14
x = 49 - 14
x = 35
x = 49 - y
let y = 35
x = 49 - 35
y = 14
