Answer:
o find total, we'll need to add all the costs! There's the cost for the phone which is paid once, monthly fee for all the months you use it.
total = 50 + (30 × months )
In this case, the question wants the equation in x and y, so we can plug those in:
y = 50 + 30x
Step-by-step explanation:
1.364 the line goes over the 3 and 6 not over the four.
5 days because there are 24 hours in a day so every six hours you can take 4 a day
Answer:
3*sqrt(3x)
--------------
2x
Step-by-step explanation:
To rationalize the denominator, we need to get rid of the square root. We need to multiply by sqrt(12x)/sqrt(12x)
9 sqrt(12x)
---------- * -----------
sqrt(12x) sqrt(12x)
9sqrt(12x)
-----------------
12x
We can cancel 3 in the top and bottom
3sqrt(12x)
---------------
4x
We also notice that 12 is made up of 4 and 3
3sqrt(4) sqrt(3x)
---------------
4x
3sqrt(4) sqrt(3x)
----------------------
4x
3*2sqrt(3x)
--------------
4x
We can cancel a 2 in the top and bottom
3*sqrt(3x)
--------------
2x
