10 minutes : 8 problems
x minutes : 60 problems
10 * 60/8 = 150/2 = 75 minutes for 60 problems
Answer:7
Step-by-step explanation:
21=42-3r
21-42=3r
-21=3r
r=7
ANSWER:
y intercept = (0,-6/5)
x intercept = (-3,0)
EXPLANATION:
To find the y intercept you have to substitute the x with zero because the y intercept always lies on the y axis which means that they will always have the coordinates (0,y)
The same goes for the x intercept. To find the x intercept you have to substitute the y with zero because the x intercept always lies on the x axis which means that they will always have the coordinates (x,0)
WORKING OUT:
Given=2x+5x= -6
The y intercept)
x=0
2(0)+5y= -6
5y= -6
y = -6/5 (divide each side of the equation by t to get the y alone)
y intercept = (0,-6/5)
The x intercept)
y=0
2x+5(0)= -6
2x= -6
x = -3 (divide each side of the equation by t to get the x alone)
x intercept = (-3,0)
Step-by-step explanation:
False
ex. 12 can be divided by 3
but it's even number
