Jack purchases 12 gallons of gas on monday. he uses 2/3 of the amount purchased commuting to and from work during the week and an additional 2 gallons running errands. how many gallons of gas does john use from work and errands?

Using operations with fractions, John uses 10 gallons from work and errands.

Solution:

Jack purchases 12 gallons of gas on Monday.

He uses 2/3 of the amount purchased commuting to and from work during the week:

(2/3)(12)=(2/3)(12/1)=(2*12)/(3*1)=24/3=8

Then John uses 8 gallons commuting to and from work during the week.

And an additional 2 gallons running errands.

John uses in total from work and errands= 8 gallons+2 gallons

John uses in total from work and errands= 10 gallons

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
