Answer:
b. 
Step-by-step explanation:

Quadratic equations are suppose to be written as: 
so the new quadratic equation for this problem will be: 
Now rearrange the terms:
Then use the Quadratic Formula to Solve for the Quadratic Equation
Quadratic Formula =
Note: Ignore the A in the quadratic formula
Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

a = 3
b = -7
c = -1

I believe, if I'm not correct but I think the answer would be 8 minutes or less.. Considering the fact that the Harris Family left 12 minutes ahead and the Arlen family is Averaging 55 MPH.. Too the speed that the Arlen's are going make the time for them to catch up to the harris's shorter. The Arlen's are going 15 mph faster sooo.. Yeah.. Tell em if this helps! :D
Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
Huh I don’t understand your question at all
Answer:
Her answer is incorrect
We have the correct feet number (5) but the incorrect inches number (should be 3 inches and not 1/4 inches)
Step-by-step explanation:
Here, we want to make a conversion from feet to inches and feet
Mathematically, we know that;
1 feet = 12 inches
So, for 63 inches, we can have a clear ;
63/12 = 5 feet + 3 inches
Hence, the correct conversion of 63 feet should be;
5 feet and 3 inches
