I need this solved please.

Answer:

slope = 10/1

Step-by-step explanation:

slope is the vertical rise over the horizontal rise

if you select two points on the line -- I used (10, 0) and (20, 20) -- and subtract the y-values you will get the vertical rise (20 - 0 = 20); if you now subtract the x-values (20 - 10 = 10) you will get the horizontal rise

so, 20/10 or 10/1

if you go from point (10, 0) to (20, 20) then you go up by 10 and over to the right by 1

puteri [66]

Answer:

15 days

Step-by-step explanation:

Since he used both of the weights today, he will only do both on the day they come together.

weights: 3 days, 6 days, 9 days, 12 days, 15 days

machine: 5 days, 10 days, 15 days

Because the numbers both were the same on 15 days, then that is when he will do both of them

8 1/4 minus 5/6 equals what??
kondaur [170]
Ok to figure it out you first find the common factor, which is 12
so the fractions become 8 3/12 and 10/12 then you subtract those 2,
8 3/12-10/12 is 7 5/12.
Hope That Helps!!!
