Hey there
SO we know that the total amount that she brought is 24 cookies.
we also know that 2/3 of the cookies are choco chip.
So to find the answer we need to divide 24/3 which gives us 8 so one third of 24 is eight if we multiply 8 by two we get 16 which is 2/3 of 24.
Answer:
Each car takes about 9 minutes to be washed.
The line is not in slope intercept form, so you need to get y by itself
15x -3y = 90
Subtract 15x
-3y = -15x + 90
Divide by -3
y = 5x -30
So, the slope (x) is 5/1.
I hope that helps!
D = (5-1)/(13-(-3)) = 0.25
f(13) = 13d + x = 13 * 0.25 + a = 3.25 + a = 5
a = 1.75
f(x) = 1.75 + 0.25x
