Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!

Allison wants to buy a game that costs $120. She has saved $30 for the game. She earns $5 per hour babysitting.
sergey [27]

Answer:

Step-by-step explanation:

<em>Cost of game = $120</em>

<em>Current savings = $30</em>

<em>Rate for babysitting (per hour) = $5/hour</em>

<em></em>

<em>So, required equation is :-</em>

<em>120 = 5h + 30</em>

<em>5h = 90</em>

<em>h = 18</em>

<em></em>

<em>She must make $90 by babysitting for 18 more hours.</em>

How do you do these 2 questions?
zavuch27 [327]

Answer:

0 ≤ an ≤ bn

The series ∑₁°° bn converges

The series ∑₁°° an converges by comparison to ∑₁°° bn.

0 ≤ an ≤ bn

The series ∑₁°° bn diverges

The comparison test is inconclusive for our choice of bn.

Step-by-step explanation:

an = 1 / (n² + n + 3) and bn = 1 / n²

The numerators are the same, and the denominator of an is greater than the denominator of bn.  So 0 ≤ an ≤ bn.

bn is a p series with p > 1, so it converges.

Since the larger function converges, the smaller function also converges.

an = (3n − 1) / (6n² + 2n + 1) and bn = 1 / (2n)

If we rewrite bn as bn = (3n − 1) / (6n² − 2n), we can tell that when the numerators are equal, the denominator of an is greater than the denominator of bn.  So 0 ≤ an ≤ bn.

bn is a p series with p = 1, so it diverges.

The larger function diverges.  We cannot conclude whether the smaller function converges or diverges.
