Answer:
(2 decimal places)
Step-by-step explanation:
Quadratic Formula: 
-----------------------------------------------

Plug in values:

First value of x:
(2 decimal places)
Second value of x:
(2 decimal places)
If (55 + x)/2 is to be 67, then 55+x = 2*67, so x = 2*67 - 55 = 79
Answer:
3 times
Step-by-step explanation:
Firstly we calculate the number of minutes between 8 and 11 am
The number of hours is 3 hours
The number of minutes is 180 minutes since 1 hour is 60 minutes
Now out of 180, to know the number of times that they both leave, we need to get the multiples of both between 0 and 180
The multiples are;
60, 120, 180
This means that they leave together 3 times
9514 1404 393
Answer:
4
Step-by-step explanation:
To find the value of g(7), locate 7 on the x-axis. Follow the grid line upward until it meets the graph (blue line). At that point, follow the grid line to the left until it meets the y-axis. Read the value from the scale on the y-axis.
g(7) = 4
857 x 132= 113,124
