Answer:

The answer to your question is ∠2 = 130°        

Step-by-step explanation:

Data

 m∠1 + m∠5 = 100

From the picture, we notice that ∠1 and ∠5 are corresponding angles so they measure the same.

                        ∠1 + ∠1 = 100

                              2∠1 = 100

                               ∠1 = 100/2

                               ∠1 = 50°

From the picture, we know that ∠1 and ∠2 are supplementary, then,

                               ∠1 + ∠2 = 180

-Solve for ∠2

                               ∠2 = 180 - 50

-Result

                              ∠2 = 130°

Given ; 2(10-13x)+9x=-34x+60
rewona [7]

Try comparing your solution with the following:

Solution:

2(10-13x)+9x=-34x+60\\(20-26x)+9x=-34x+60\\20-26x+9x=-34x+60\\20-17x=-34x+60\\20-60=-34x+17x\\-40=-17x\\x=\frac{40}{17}

Answer:

x=\frac{40}{17}

Check:

2[10-13(\frac{40}{17})]+9(\frac{40}{17})=-34(\frac{40}{17})+60\\-20=-20

<em>Hope this was helpful.</em>

This makes no sense, help pls
stiv31 [10]

Please mark me branliest!

**Answer**

16 if you want exact, 20 if you want a little over.

**Explanation**

So check this... it's $50 per student that attends the camp, right?

(Nod if you're with me.)

The dude buys 5 dozen donuts for 16 days. 50 x 16 = 800

5 dozen is the same as 50 donuts.

You multiply to get the total amount of donuts he buys in the total days (16).

Each 10 donuts costs 10 dollars.

If the dude buys 800 donuts it cost him $800.

And it costs 50 dollars for someone to go to camp.

So you divide 800/50 = 16 students

Now the problem says "In order to break even" I'm not sure what that means. But I'm assuming it doesn't want 16 then, because the price of 16 students would be the same (even) as the price of donuts that Mr. Brook buys. In that case it would be 20.

You are very welcome!!
