Answer:
17.6
Step-by-step explanation:
Formula= sumfx÷sumf
sumfx= 63×0+34×0+27×1+13×2=53
sumfx=0+0+1+2=3
53÷3= 17.6
final answer =17.6
Answer:
It will take them both 24 minutes to mow the lawn if they are working together.
Step-by-step explanation:
Given that Sam can mow a lawn in 40 minutes, and Melissa can mow the same lawn in 80 minutes, to determine how long does it take for both Sam and Melissa to mow the lawn if they are working together, the following calculation must be performed:
1/40 + 1/60 = 1 / X
3X + 2X = 120
X = 120/5
X = 24
Thus, it will take them both 24 minutes to mow the lawn if they are working together.
Answer:
1: Yes because it is in the form y=mx+b
2: Yes because it is in the form y=kx

Answer:
1 7/33
Step-by-step explanation:
6/11 + 2/3 --> We need a common denominator
--> 11 x 3 = 33
33 is our common denominator
6 x 3 = 18
2 x 11 = 22
18/33 + 22/33 = 40/33
Convert to a mixed number
=> 1 7/33
Thus, we have our answer.
Answer:
The equation of the line would be y = -5/2x - 1
Step-by-step explanation:
In order to find the equation of the line, we first need to find the slope of the original line. We can do that by solving for y.
5x + 2y = 12
2y = -5x + 12
y = -5/2x + 6
Now that we have a slope of -5/2, we know the new slope will be the same since parallel lines have the same slope. So we can use it along with the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 4 = -5/2(x + 2)
y - 4 = -5/2x - 5
y = -5/2x - 1
