Brian is choosing between two exercise routines.
In Routine #1, he burns 20 calories walking. He then runs at a rate that burns 8.5 calories per minute.
In Routine #2, he burns 38 calories walking. He then runs at a rate that burns 6.25 calories per minute.
For what amounts of time spent running will Routine #1 burn fewer calories than Routine #2?
Use t for the number of minutes spent running, and solve your inequality for t.

i would need to see the dot plot : )

step-by-step explanation:

compare

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
