Answer:
27 and 23
Step-by-step explanation:
We can solve this problem as a system of equations. X is the first number and Y is the second number.
The first equation is x+y = 50 and the second equation is x-y=4
Now we solve the system, using elimination method:
x+y=50
x-y=4
2x = 54
x = 54/2
x = 27
And from any of the equations we can find Y
27 + y = 50
y = 50 - 27
y = 23
1 hours is equal to 60 minutes.
2 hours = 120 minutes
40% is 120 minutes = 120*40/100 = 48 minutes
Answer:
2nd option
Step-by-step explanation:
The zeros are the points on the x- axis where the graph crosses.
Since the graph crosses the x- axis at x = - 1 and x = 5, then
The zeros are x = - 1 and x = 5
