Answer:

$f$ = 78

$g$ = 3.5

Step-by-step explanation:

First we need to find $f$ .

We can use the equation $72 + (f + 30) = 180$ to solve for $f$ .

We can then change that equation to $72 + f + 30 = 180$ , since the Commutative Property of Addition says that you can have any addition in any order.

Now, we can solve the equation.

$102 + f = 180\\(102 - 102) + f = 180 - 102\\f = 78$

Now that we solved $f$ , we can now solve for $g$ .

Since 25 equals $8g -3$ , we can solve the equation $8g - 3 = 25$ .

Here is how you solve it:

$8g - 3 = 25\\8g + (-3 + 3) = 25 + 3\\8g = 28\\g = \frac{28}{8}$

Since $\frac{28}{8}$ equals 3.5, which is the simplest form, that is the answer.

Hope this helps, and please mark me brainliest! :)
