If there were 10 strawberry cupcakes then chocolate would have the same number as 10= 1/2. Then 2/4 can be simplified to 1/2 meaning that Rick are 1/2 of 10 and 1/10 is just one out of the 10 strawberry cupcakes.

kenny6666 [7]

Answer:

65 miles

Step-by-step explanation:

There are two simultaneous equations . Remeber that v=d/t, 1hour = 60 minutes.

1. 40 = (d+15)/(t+0.5)

2. 50 = d/t

solving: d= 25 miles and t=0.5 hours.

The distance traveled is:

D=d+d+15

D=65 miles

Solve for X in the 2nd equation:

x+2z = 0

Subtract 2z from both sides:

x = -2z


Replace x in the first equation with -2z

-2z +y -z = 1

Combine like terms:

-3z +y = 1

Add 3z to both sides:

y = 3z +1


Replace x and y in the 3rd equation:

2(-2z) + 2(3z+1) = 4

-4z + 6z + 2 = 4

2z +2 = 4

2z = 2

z = 1


Now replace z with 1 in the other equations for x and y:

x = -2z = -2(1) = -2

y = 3z +1 = 3(1) +1 = 3+1 = 4


So you have x = -2, y = 4 ans z = 1


The answer would be written as (-2,4,1)
