Answer:
Step-by-step explanation:
This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.
tanks of gas different tanks of gas
========== = ================
hours different hours.
initial tank of gas = 3/4 tank
initial hours = 9/2 = 4.5 hours
final tanks of gas = X
final time = 12 hours.
Solution
3/4 x
==== = ==============
4.5 12
Cross multiply
4.5x = 12*3/4 Combine the right
4.5x = 36/4 Simplify
4.5x = 9 Divide both sides by 4.5
x = 9/4.5
x = 2
So she will need 2 tankfuls.
Answer:
3/4 hours
Step-by-step explanation:
3/4 = 0.75
For this case we have the following expression:
We must find a term that is a common factor for both terms of the given binomial.
We then have that for 4x, the factored expression is given by:
Answer:
The factored form of given expression is:
Option 2
Answer:
(0,-1), y, 3, 3 up, 1 right
(0,1), y, 1 up, 1 right
Step-by-step explanation:
just fill in the blanks in the order of these answers
The expression for the perimeter would be
2(x) + 2(2x+7)
which can be simplified to 2x+4x+14
which equals 6x+14
