Answer:
$3.22 per square feet
Step-by-step explanation:
To solve, I usually set up an equation:
<u>sq ft</u> = <u>12 1/2</u> = <u> 1 </u>
$ 40.21 x
Then, use cross multiplication.
(12 1/2)x=40.21
Divide both sides by 12 1/2 or 12.5
x = 3.2168
Round to the hundredths place [because we're dealing with money]
$3.22
I hope this helps!
35+25=60
y=60
If you add the opposite side values of the triangle (not the one touching the y), you get the value of y). 35+25=y
This works because y+x= 180 and the three angles of a triangle add to 180.
Answer:
Step-by-step explanation:Here the slope of the line = m = 2
The line passes through the point (
x
1
, y
1
) = ( , 9
).
The equation of the line with slope m and passing through the point (
x
1
, y
1
) is given by
(
y
- y
1
) = m (
x - x
1
)
(
y - 9
) = 2 ( x - 3
)y - 9 = 2
x - 6
Collecting terms in one side
0 = 2
x - y - 6 + 9
2
x - y + 3 = 0
Hope this helps x
Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
