Answer 2 more questions ! you in advance! 1. in the equation, 4(x + 5) - 2x + 4 = 16, what are some of the steps that should be taken to solve for x? select all that apply. a. distribute the 4 among the terms inside the parentheses b. combine like terms c. subtract both sides of the equation by 5 d. divide both sides of the equation by 2 2. what is the value of x in the equation 7(3x - 13) = 224? a. 32 over 3 b. 15 c. 19 over 3 d. 32

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.
