If a=2b=3c=6, find the value of
a+2b-4c how to calculate this one

4

Step-by-step explanation:

Based on the equation you are given, calculate the values of a, b, and c. Then substitute each value for the corresponding variable and use the correct order of operations.

a = 2b = 3c = 6

a = 6

2b = 6, so b = 3

3c = 6, so c = 2

a + 2b - 4c =

= 6 + 2(3) - 4(2)

= 6 + 6 - 8

= 12 - 8

= 4

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.
