Question

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

Answer 1

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:

$7h+15.75=57.75\\ 7h=42\\ h=\frac{42}{7} \\ h=6$

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

Answer 2

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

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

$2h+4.5=\frac{57.75}{3.5}=16.5$

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:

$h=\frac{12}{2}=6$

Therefore, Option A is the correct answer.
