Answer:

B. 49.99(3) + 49.99(1.25)(m − 3) + 10m

Step-by-step explanation:

Let's do this step by step.

Initially, it costs $49.99 a month, for the first three months.

49.99(3)

After three months, the company increases price by 25%. So with m=month, that means that after three months, the price is 1.25% of what it was before. We multiply 49.99 times 1.25 to find the new price.

49.99(3) + 49.99(1.25)(m-3)

They also charge $10 a month.

49.99(3) + 49.99(1.25)(m-3) + 10m

|3k-2|=2|k+2| how do I do this when the 2 is on the other side??
grin007 [14]
|3k-2|=2|k+2l
Do Distributive Property and take 2 times by everything in the parenthesis. That will leave you with |3k-2|=2k+4. Then add like terms. 3k+2k=5k. Then -2+4=2. So you end up with 5k+2. I believe I'm right. If not please tell me.

14 – (2y + 5) = -2y + 9
patriot [66]

Answer:

The answer is all real numbers

Step-by-step explanation:

Simpify both sides of the equation: 14−(2y+5)=−2y+9

14+−1(2y+5)=−2y+9(Distribute the Negative Sign)

14+−1(2y)+(−1)(5)=−2y+9

14+−2y+−5=−2y+9

(−2y)+(14+−5)=−2y+9(Combine Like Terms)

−2y+9=−2y+9

−2y+9=−2y+9

Then add 2y to each side. −2y+9+2y=−2y+9+2y

9=9. Then subtract 9 from each side. 9-9=9-9=0. That means that all real numbers is the answer.
