Answer: 2x-5

Step-by-step explanation:

Group like terms. (7x-5x) and (-25+30)

7x-5x is 2x.

The 25 becomes negative due the sign in front of it. -25+30=5.

You cannot solve unlike terms, so your answer is 2x-5.

A small town's raffle has 85 entries and 3 gift baskets that three different people could win. What is the probability of winnin
mr_godi [17]

Answer:

<h2>0.035</h2>

Step-by-step explanation:

This problem is on probabilty since there are a number of entries to be selected from which are 85 entries, the chances of winning one of the prices if selected is

the number of entries you have/ total number of entries

given that the total entry is 85

and that you have one entry

Since there are three gift baskets you have three chances to win one.

hence there will be a total of three draws, and after each draw, there won't be a replacement of the previous winner (as the winners are three distinct persons).

Hence the probability of winning a draw for the gift basket is  

=1st draw+2nd draw+3rd draw

= 1/85+1/84+1/83

= 0.0117+0.0119+0.012

= 0.035

Which of these points lies on the line described by the equation below? y+8=-4(x+7)
timama [110]
D. (-8,-7) Simplifying<span>y + -8 = 4(x + 7) Reorder the terms: -8 + y = 4(x + 7) Reorder the terms: -8 + y = 4(7 + x) -8 + y = (7 * 4 + x * 4) -8 + y = (28 + 4x) Solving -8 + y = 28 + 4x Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + y = 28 + 8 + 4x</span>
