The length of three sides of a triangle are 3x + 1/2, 2x +1/4, and x +1/2.Use the drop-down menu to complete the answer.

Answer 1

Answer:

Answer: x= 41

Explanation: Angles 1 and 2 have to equal 180° since they are supplementary. So you put 3x+2x-25=180, you then add like terms. 5x-25=180 Then you have to isolate x, so you add 25 to both sides of the equation. 5x=205, then you divide both sides by 5. So your answer is x=41.

You can check to make sure by plugging in x for 41 .

Hope this helps!

Brand W: 500 napkins for $2.87Brand X: 200 napkins for $1.27
Brand Y: 100 napkins for $0.62
Brand Z: 250 napkins for $1.37

Which brand is the cheapest? What is the cost of one napkin of this brand?

Which brand is the most expensive? What is the cost of one napkin of this brand?

Answers

The best way, in my opinion, to do this, is to find the unit rate of each napkin brand, or the cost per napkin. To do this, divide the money amount by the amount of napkin they give you.

/Brand W:2.87/500=.00574 \
\Brand X: 1.27/200=.00635   \ These are the
/Brand Y: .62/100 =.0062   / cost per napkin.
  \Brand Z: 1.37/250=.00548 /

Which one out of these 4 values is the lowest value? Obviously the two with the 6 in the thousandths place are more expensive than the ones with the 5s in the thousandths place, so that already eliminates Brand Z and Brand W.

What do we have left?

Brand X: 1.27/200=.00635
Brand Y: .62/100 =.0062
Cool. Which of these is a smaller number? Tip: If the first number besides 0 is the same, check the next one! You should get that Brand Y is the cheapest! :) Hoped this helped!

1 batch . . . . 2-1/4 cups
2 batches . . 4-1/2 cups
3 batches . . 6-3/4 cups
4 batches . . 9 cups
.

7 batches . . 7(2 + 1/4) =

   (7 x 2) + (7 x 1/4) =

   14    + ( 7/4) =

   14 + 1-3/4 = 15-3/4

c). Write a proportion:    (1 batch) /(3 dozen) = (x) / (200 cookies)

1 dozen = 12 cookies
3 dozen = 36 cookies

So the proportion is (1 batch)/(36 cookies) = (x) / (200 cookies)

Cross-multiply:    (1 batch) x (200 cookies) = ('x' batch) x (36 cookies)

Divide each side by (36 cookies):

   (1 batch x 200 cookies / 36 cookies) = 'x' batch

   (200 batch / 36) = 'x' batch

   x = 200/36 = 5.55 batches

If you can only make whole batches, then you need to make 6 of them
in order to have at least 200 cookies.

d). There's more than one possible unit rate here:

--   2.25 cup flour per batch

-- 0.75 cup flour per dozen cookies

-- 0.0625 cup flour per cookie

-- 16 cookies per cup flour

-- 0.444 batch per cup flour

etc.

What is the length of the longest side of a triangle that has the vertices (-5, 6), (-5, -2), and (1, -2)? Round to the nearest hundredth, if necessary

Answers

Well you'd use the distance formula for each pair of points:

d = sq.root of((x2 - x1)^2 + (y2-y1)^2)

(1) For the points (-5,6) and (-5,-2):

d = sq.root of((-5-(-5))^2 + (-2-6)^2)
= sq.root of (0 + 64)
= 8

(2) For the points (-5,-2) and (1,-2):

d = sq.root of((1-(-5))^2 + (-2-(-2))^2)
= sq.root of (36 + 0)
= 6

(3) For the points (1,-2) and (-5,6):

d = sq.root of((-5-1)^2 + (6-(-2))^2)
= sq.root of(36 + 64)
= sq.root of(100)
= 10

Therefor the length of the longest side is 10 units

Answers

a mixed number consists of a regular interger (full number) and a fraction. For example 1 2/3

It has a number with a fraction right next to it.

It is pretty much the difference between 12 and 15. And that would be 3. If this is right could you possibly give me brainliest? Hope this helped.
