Q/13 + 11 = 13 Please show me a step by step

q=22

Step-by-step explanation:

it will take me a sec to explain hang on

26

Step-by-step explanation:

Solve for q:

q/13 + 11 = 13

Put each term in q/13 + 11 over the common denominator 13: q/13 + 11 = q/13 + 143/13:

q/13 + 143/13 = 13

q/13 + 143/13 = (q + 143)/13:

(q + 143)/13 = 13

Multiply both sides of (q + 143)/13 = 13 by 13:

(13 (q + 143))/13 = 13×13

(13 (q + 143))/13 = 13/13×(q + 143) = q + 143:

q + 143 = 13×13

13×13 = 169:

q + 143 = 169

Subtract 143 from both sides:

q + (143 - 143) = 169 - 143

143 - 143 = 0:

q = 169 - 143

169 - 143 = 26:

| q = 26

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

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.
