A) Amount of money earned by seji = s
Amount of money earned by Gavin = g
So, equation would be: s+g = 425
B) Solving the system: s+g = 425
we know, g = s+25
Substitute it into the equation:
s+s+25 = 425
2s = 400
s = 200
so, g = 200+25 = 225
C) Graph for the equation, Mark (s,g) = (200,225) then, draw the line from the origin.
D) Seiji earned = $200
Gavin earned = $225 [ Solved in B part ]

In this case, we must use trigonometry to find the value of x:
Thus the value of x rounded to the nearest tenth is <u>8.2</u>

Answer:
x > 3 1/5
Step-by-step explanation:
5x +3>19
Subtract 3 from each side
5x +3-3>19-3
5x >16
Divide each side by 5
5x/5 > 16/5
x > 16/5
x > 3 1/5
The answer is 4/105
Explanation
Answer:
32.25%
Step-by-step explanation:
The equation of variation is z = ky/√x
When y is increased by 15%, we have value of y = 1.15y.
To keep z constant √x must = 1.15 so x must be 1.15^2 = 1.3225.
Therefore x must be increased by 0.3225 or 32.25%.
