Elmer and Elvin are emptying an 800 gallon tank while they fill a 1000 gallon - tank. They empty at the rate of 15 gallons per minute and fill at the rate of 25 gallons per minute. After how many minutes will bothe tanks contain the same number of gallons?

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

what is the approximate solution for the system of equations x+5y=10 and 3x+y=1

step-by-step explanation:

tell me the answer first then i will answer it

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
