Translate the following sentence into an equation. the product of five and the sum of a number x and three is twelve.

a) 5 + 3x = 12
c) 5x + 3 =12
b) 5(x + 3) =12
d) 5x + 3 = x

Option B

The product of five and the sum of a number x and three is twelve is 5(x + 3) = 12

Solution:

Given that we have to translate the following sentence into equation

Given sentence is:

The product of five and the sum of a number x and three is twelve

Let the number be "x"

By given sentence,

product of five and the sum of a number x and three = 12

"Product" means multiplication and "sum" means addition

So multiplication of five and sum of x and 3 is 12

Thus Option B is correct

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.

answer

false
