Question

Which is the solution to the equation 3.5(2h+4.5)=57.75? Round to the nearest tenth if necessary

A.6B.7.6C.8.9 D.10

Answer 1

The equation given to us is:
`3.5(2h+4.5)=57.75`

TO solve for
`h`, first divide both sides by 3.5

`2h+4.5=(57.75)/(3.5)=16.5`

Subtracting 4.5 from both sides we get:

`2h=16.5-4.5=12`

Finally, dividing both sides by 2, we will get the value of h as:

`h=(12)/(2)=6`

Therefore, Option A is the correct answer.

Answer 2

The answer is the option A, which is: A.
`6`

The explanation for this problem is shown below:

1. You have the following equation:

`3.5(2h+4.5)=57.75`

2. Apply the distributive property and solve for
`h`, as following:

`7h+15.75=57.75\\ 7h=42\\ h=(42)/(7) \\ h=6`

As you can see, the correct answer is the option mentioned before.
