Answer:
$105 (Make sure to read the explanation)
Step-by-step explanation:
120.45 + 95.75 + 105.32 + 140.25 + 89.68 + 101.32 = 652.77
652.77 ÷ 6 = 108.795
I think the mean as her budget is a tiny weny too high so I think $105 is a good enough budget. Feel free to change it.
For this one you want to cancel out the x-terms.
Multiply top equation by -2
---> -2x -10y = 6
---> 2x +7y = 3
Add them together
---> -3y = 9
Solve for y ...
Density is mass/volume.
40.5g/15.0mL = 2.7g/mL
The length is 8. the width is 32.
32(2) = 64
8(2) = 16
64+16 = 80
So the length would be 8 and the width would be 32 since it's 4 times the length.
Hope this helped!
Answer:
Step-by-step explanation:
The point slope form of a line is 
where 
. We write
Since the line is parallel to the line shown it will have the same slope. To find m, count the slope from each marked point on the graph. Count the rise then the run and create a fraction rise/run. The slope is 6/4 which simplifies to 3/2. Now substitute it for m.
