Ok i really hate 8th grade IXL's so please help me

1

Step-by-step explanation:

He has 4 cups remaining with 4 tables set

If he sets one more table he'll have 3 cups remaining as he sets the cup with the table.

I feel you IXL really sucks

1 table

Step-by-step explanation:

If you draw a line form the 3 on the y-axis and the numbers from the x-axis you can see that 3 (on the y axis) and 1 (on the x axis) intersect this shows that its 1 table.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
