Answer:
6 hours
Step-by-step explanation:
A: y=125+7x
B: y=110+10x
for A to be a better deal than B, 125+7x<110+10x has to be true
- subtract 7x from both sides and subtract 110 from both sides of the inequality: 15<3x
- divide by 3: 5<x
- so x has to be greater than 5, im pretty sure it's 6 hours but it might also be 5 depending on how it's taught for you
Answer:
q<392
Step-by-step explanation:
First, we turn words into an inequality. Then, we solve for q.

It is also a good idea to check our answer, to make sure it is reasonable and we did not make a careless mistake.

The value satisfies the equation, so this should be correct.
Answer:
1/2-1/2, 3
Step-by-step explanation:
Notice that the ratio of the first and second terms is the same as that between the third and fourth terms. So this cubic will factor by grouping:
By "inspection" you can write the equation as
.. x + y = 10
Then
.. y = -x +10 . . . . . . . . the desired form
