Which is the best interpretation of the solution set for the compound inequality? x – 1 < 2x + 4 or 3(negative StartFraction 3 over 2 EndFraction x minus 1 less than 2 x plus 4 or 3 left-parenthesis StartFraction 2 over 3 EndFraction x plus 1 right-parenthesis less than 11.x + 1) < 11

no solution
x > –10
x < 4
all real numbers

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
