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 ]

Hope this helps!

Find the value of X round your number to the nearest tenths<br><br><br> Explain it please
Anarel [89]

In this case, we must use trigonometry to find the value of x:

        tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!

If z varies directly as y and inversely as the square root of x, by how much should x be increased so that z is kept constant wh
Norma-Jean [14]

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%.
