Answer:
x/y = 3/8
Step-by-step explanation:
y = 4/5 = 8/10, so ...
x/y = (3/10)/(8/10) = 3/8
_____
One way to divide fractions is to make them have the same denominator. Then their ratio is the ratio of their numerators.
Answer:
x + y = 15
y = 3x + 1.5
x + (3x + 1.5) = 15
Step-by-step explanation:
Let :
Soft ball practice = x
Soccer practice = y
y = 3x + 1.5
Total practice time :
x + y = 15 - - - (1)
x + 3x + 1.5 = 15
4x + 1.5 = 15

Answer:
Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to 
substituting the value of y in 
:
substituting x=-1 in y= -4-5x:
(upon solving, you should get this)
2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)
-1= 2 x 1 +c
-3=c
