Kallie drank 12.75 gallons of water in 3 weeks. She drank the same amount of water each day. Estimate how many gallons she drank in one day.

607 miltliters per day

Step-by-step explanation:

Step one:

given data

Kallie drank 12.75 gallons of water in 3 weeks

if she drank the same amount each day, then in one day she will drink

Notethere are 31 days in 3 weeks (7 days make 1 week)

Step two:

Hence in one day she will drink

= total volume of water/number of days

= 12.75/21

=0.607liters per day

or

607 militliters per day

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
