Answer:
3:20
Step-by-step explanation:
You can solve this problem by subtracting the movie length from the end time. This can be done in steps.
If you subtract 1 hour from 4:40, you are left with 3:40.
4:40 - 1 hour = 3:40
If you subtract 20 minutes from 3:40, you are left with 3:20.
3:40 - 20 minutes = 3:20
It would be 10, because its s s2 and s to the square root of three :)
Answer:
Bill is 25 years old and Jenny is 29 years old
Step-by-step explanation:
Systems of Equations:
J = 4 + B
J + B = 54
Substitute J into the first equation.
4 + B + B = 54
Add like terms.
4 + 2B = 54
Isolate the variable.
4 + 2B = 54
-4 -4
2B = 50
2B/2 = 50/2
B = 25 years old
Plug in B into the second equation of the system.
J + B = 54
J + 25 = 54
Isolate the variable.
J + 25 = 54
-25 -25
J = 29 years old
Check your answer. Pick whatever equation in the system and plug in your answers.
J = 4 + B
29 = 4 + 25
29 = 29
