Answer:
The exponent of the second term (b) starts with 0 (b0 = 1) and then increases by one in each following term until it is equal to the exponent of the binomial (5).

Answer:
10 hours lifeguarding, 6 hours tutoring
Step-by-step explanation:
As you know how long he worked and how much he earned, it's worth seeing how many hours it would have been had he worked just tutoring or just lifeguarding.
$242 / 11 = 22 hours if it was just lifeguarding
$242 / 22 = 11 hours (as it's exactly double the wage) if it was just tutoring
We now know that he worked some combination of both
Calculating his average wage can help work out which he worked more of:
$242 / 16 = 15.125
That means Parker's average hourly wage was 15.125 which is closer to 11 than 22 (16.50 would mean an exactly even split between the two) so he did more hours lifeguarding than tutoring so more than 8 hours.
What I then do is consider the variations that could work:
9 (lifeguarding) and 7 (tutoring) = 99 + 154 = 243
So we're almost exactly there straight away, but not quite so...
10 and 6 = 110 + 132 = 242
There you have it.
Answer:
D. 3x + 1 < x + 3
Step-by-step explanation:
Assuming the number to be x
Three times a number = 3x
1 more than 3 times a number = 1 + 3x
The symbol for less than is = <
The sum of 3 and the same number = x + 3
After assembling the given data, the equation will be:
3x + 1 < x + 3
[The options given in the question are incorrect. The correct options will be:
A. 3x + 1 = x + 3
B. 3x − 1 = x + 3
C. 3x − 1 > x + 3
D. 3x + 1 < x + 3 ]
∴ Option D is the correct answer.
