Percentage</h3>
Percentage is used to express a fraction number or decimal in fraction of hundred. It is given by:
Percentage = [(new value - original value) / original value] * 100%
Let x represent the new value and y represent the original value, hence:
30% = [(x - y)/y] * 100%
0.3 = (x - y)/y
x - y = 0.3y
x = 1.3y
The new value after the original value is increased by 30% is 1.3 times the original value.

Answer:
x = 15
y = 6
z = 10
Step-by-step explanation:
Okay, let's set up the equation(s).
x = 3 + 2y
x = 3/2z
x + y + z = 31
With some algebra that God knows how came through my mind, I got this:
x = 15
y = 6
z = 10

Answer:
D. Henry's started farther, went faster
Step-by-step explanation:
Henry's balloon traveled 18 additional miles (from 30 to 48) in 2 hours, so had a speed of 18mi/(2h) = 9 mi/h. The equation for his position could be ...
y = 9x +30 . . . . . 9 is the rate of change; 30 is the initial value
__
Comparing this to Tasha's position function, we see her balloon started 20 miles from town and traveled 8 miles per hour.
__
Henry started farther from town and traveled faster.
