Emily = x
Samantha = x + 2
Lauren = x + 4
x + (x + 2) + (x + 4) = 42
x = 12
Thus:
Emily = 12
Samantha = 14
Lauren = 16
Answer:
B. y = -5/2x +3/2
Step-by-step explanation:
5x + 2y = 3
We want to get this in the form
y = mx +b where m is the slope and b is the y intercept
Subtract 5x from each side
5x -5x+ 2y =-5x+ 3
2y = -5x+3
Divide by 2
2y/2 = -5x/2 +3/2
y = -5/2 x +3/2
(17.5)(x)=125
Divide each side by 17.5 leaving the equation as x=7.14
