Dad arrived home at 4:50 p. m. He left work 40. Minutes ago. What time did dad get off work

4:10 p.m.

Step-by-step explanation:

4:50 p.m.

60 minutes in an hour

4:50 - 40 = 4:10

4:10pm

Step-by-step explanation:

If he left 40 minutes ago and arrived at 4:50pm, then we must subtract the 40 minutes from the time, 4:50pm.

Remember we are subtracting minutes, not hours so we will only subtract from the minutes on the time, which displays 50.

50 - 40 = 10

4:10pm

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
