Answer:
1)
2x = 16
16 ÷ 2 = 8
x = 8
2)
2 + x = 28
28 - 2 = 26
x = 26
3)
3 ÷ 6 = 0.5 (I'm not sure about this one)
4)
27 - 10 = y
27 - 10 = 17
y = 17
5)
1/3 = 400 cal
400 + 400 + 400 = 1, 200
whole pizza = 1,200 calories
6)
$287 - $175 = $112

Answer:
The farthest distance would be 32.5 miles
Step-by-step explanation:
Given,
Speed = 65 miles per hour,
If t represents the time ( in hours ) taken in travelling,
Since, time has to commute down less than 30 minutes,
Also, 1 hour = 60 minutes,
Thus,
i.e. the highest time taken = 1/2 hours,
We know that,
Distance = speed × time,
∵ Distance ∝ time,
⇒ Distance will farthest for largest time taken,
Hence, the farthest distance = 
= 32.5 km.
Answer: 15
Step-by-step explanation:
Let's define the concept of inverse functions.
If we have a function h(x), such that it has an inverse, and:
h(x) = y.
Then the inverse function j(x) must meet the following:
j(y) = x.
Now, we want to calculate:
h( j(15) ).
Let's suppose that:
j(15) = A.
(Where A can be any real number).
then, by the above relation, we must have that:
h(A) = 15.
Now we can replace j(15) by A in h(j(15)):
h( j(15) ) = h( A ) = 15.
