Answer: $ 12.05
Step-by-step explanation:
Answer:
The answer would be 10.72
Step-by-step
You already have two side lengths so you use those to find the 3rd length
+


196-81=115

10.72
4(1/4)+3(5/8)=
(4+3)+(1/4+5/8)
7+(2/8+5/8)
7+7/8
7 and 7/8
Hope I didn't mess up for your sake
For the first question, all you have to do is substitute the values. for example g(x)=-5x+2 becomes g(-1)=-5(-1)+2
So you want to get all of the unknowns on one side and all the kknowns on the other (this only works with one placeholder)
with equation you must do the same thing to both sides (except divide by 0 which is not allowed and undifined) so that the equation stays equall so
14y-51=187+4y
so add 51 to both sides
14y=238+4y
subtract 4y from both sides
10y=238
divide both sides by 10
y=23.8
(y=17 would make the equation false)
answer is y=23.8
