1/3x=x-22
Add 22 to both sides to get 22+1/3x=x
Subtract 1/3x from both sides to get 22=2/3x
Multiply each side by 3/2 to get x=33!

Answer:
f(3) just means to substitute 3 in for x.
Step-by-step explanation:
f(3) just means to substitute 3 in for x.
f
(
3
)
=
−
2
Explanation:
f
(
3
)
=
−
(
3
)
2
+
7
According to the order of operations, first square the 3, which is 9.
f
(
3
)
=
−
9
+
7
The negative sign in front of the x squared is equivalent to multiplying by negative one.
Add -9 and 7 together, which is -2
So,
f
(
3
)
=
−
2
Mean is the same as average. Adding up all the amounts then dividing it by the number of amounts. In this case, we add up all the snowfall amounts and then we divide it by 10 ( the count or number of snowfall amounts).
In equation,
(13+19+16+23+11+18+14+26+13+16) / 10 = 16.9
Th answer is A. 16.9 inches.
