Answer:

[tex]f[/tex] = 78

[tex]g[/tex] = 3.5

Step-by-step explanation:

First we need to find [tex]f[/tex].

We can use the equation [tex]72 + (f + 30) = 180[/tex] to solve for [tex]f[/tex].

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

Now, we can solve the equation.

[tex]102 + f = 180\\(102 - 102) + f = 180 - 102\\f = 78[/tex]

Now that we solved [tex]f[/tex], we can now solve for [tex]g[/tex].

Since 25 equals [tex]8g -3[/tex], we can solve the equation [tex]8g - 3 = 25[/tex].

Here is how you solve it:

[tex]8g - 3 = 25\\8g + (-3 + 3) = 25 + 3\\8g = 28\\g = \frac{28}{8}[/tex]

Since [tex]\frac{28}{8}[/tex] equals 3.5, which is the simplest form, that is the answer.

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