Answer:
-14
Step-by-step explanation:
We must isolate x by itself for solve for its value. To do so, we must subtract 5 on left side. What we do to one side, we do to the other side, so we subtract 5 from right as well. However, on right side, two negatives means we actually end up adding (and keeping the negative sign) and thus you get -14.
X + 5 - 5 = -9 -5
X = -14
Answer:
2 5/6
Step-by-step explanation:
Find a common denominator. In this case, it's 12
5 9/12 - 2 11/12
borrow, kind of, but for fractions
4 21/12 - 2 11/12
subtract like normal
2 10/12
simplify
2 5/6
Answer:
40
Step-by-step explanation:
2 cups = 1 pt
therefore
1/2 is the equation
...
80/2 = 40
So u plug in both values of x
f(4)=12+4/5(4)= 15.2
f(8)=12+4/5(8)= 18.4
then u add the 2 answers together
15.2+18.4 = 33.6
then divide by 2
33.6/2=16.8
