Which of the following ratios are equivalent to 34:21?

4(x-1)=8(x-2)

multiply the first bracket by 4

(4)(x)=4

(4)(-1)=-4

multiply the second bracket by 8

(8)(x)=8x

(8)(-2)=-16

4x-4=8x-16

move 8x to the other side ( in other words combine like terms)

sign changes from +8x to -8x

4x-8x-4=8x-8x-16

-4x-4=-16

move -4 to the other side

-4x-4+4=-16+4

-4x=-12

divide both sides by -4 to get x by itself

-4x/-4=-12/-4

x=3

answer:

x=3

Answer:

x = 3

Step-by-step explanation:

4( x - 1) =8

4x - 4 = 8

   + 4  + 4

4x = 12

x = 3

8 ( x - 2 )

8 ( 3 - 2 )

24 - 16

= 8

Answer:

3.1%

Step-by-step explanation:

53.80/1625 x 100 is 3.1

Hope this helps plz hit  the crown ;D

So what you can do is divide 53.10 by 1735 to get percentage

0.0306051873 is your decimal, so move it right 2 places to get

3.06% of his money.

You asked for the nearest 10th of a percent, so you round that to

3.1%

Answer rounded by nearest thousand

1.085

Answer rounded by nearest day

2

Step-by-step explanation:

25/135

          make into a unit fraction

0.185/1

            multiple by ten

1.85/10

Answer:

Sherry have 8 crayons.

Step-by-step explanation:

Marie has 32 crayons.

Sherry has 1/4 as many crayons as Marie.

We need to find how many crayons does Sherry have. It means we need to find 1/4 of 32. Let the answer is x.

[tex]x=\dfrac{1}{4}\times 32\\\\=8\ \text{crayons}[/tex]

Hence, Sherry have 8 crayons.

Answer: It seems like you're correct, maybe try switching the numbers around if you haven't done so.

When it's say "find the product _ and _, you'll basically be writing a multiplication expression as your answer.

Answer:

28

Step-by-step explanation: This should be 28. 42 divided by 3 is 14. Why would you divide it by 3? Because the full ratio is 2:3. So 42 divided by 3 is 14. Then you add fourteen twice, for the two in the ratio. Fourteen plus fourteen is 28.

Step-by-step explanation:

Answer:

Step-by-step explanation:

s= 2, 2 and 11

I= 2, 5 and 3

u=2, 7 and 5

t= 2, 2, 3 and 3

b= 2, 2, 5 and 5

n= 2, 2, 19

p= 2, 3, 3 and 5

o= 2, 2 and 17

r= 3, 3 and 11

m= 2, 3, 3 and 7

d= 2, 3 and 7

e= 2, 2, 3 and 11

Given:

Line segment NY has endpoints N(-11, 5) and Y(3,-3).

To find:

The equation of the perpendicular bisector of NY.

Solution:

Midpoint point of NY is

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-11+3}{2},\dfrac{5-3}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-8}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-4,1\right)[/tex]

Slope of lines NY is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-3-5}{3-(-11)}[/tex]

[tex]m=\dfrac{-8}{14}[/tex]

[tex]m=\dfrac{-4}{7}[/tex]

Product of slopes of two perpendicular lines is -1. So,

[tex]m_1\times \dfrac{-4}{7}=-1[/tex]

[tex]m_1=\dfrac{7}{4}[/tex]

The perpendicular bisector of NY passes through (-4,1) with slope [tex]\dfrac{7}{4}[/tex]. So, the equation of perpendicular bisector of NY is

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-1=\dfrac{7}{4}(x-(-4))[/tex]

[tex]y-1=\dfrac{7}{4}(x+4)[/tex]

[tex]y-1=\dfrac{7}{4}x+7[/tex]

Add 1 on both sides.

[tex]y=\dfrac{7}{4}x+8[/tex]

Therefore, the equation of perpendicular bisector of NY is [tex]y=\dfrac{7}{4}x+8[/tex].

Answer: :) hi! <3

Step-by-step explanation:

Answer:

97%

Step-by-step explanation:

If you get 100% on a test, you got all the answers correct.

It doesn't matter how many questions there are. If you got all of them correct, you get 100%.

What if you have 100 questions on a test?

If you got 85 questions correct, on a 100 question test, your grade would be 85%.

If you got 35 questions correct, on a 100 question test, your grade would be 35%.

If you got 98 questions correct, on a 100 question test, your grade would be 98%.

If you count 100 trees, and 97 of them were evergreen, the percentage of trees that are evergreen would be 97%.

Answer:

total population of school = 1000

1000 - 450 males = 550 female students

550 - 200 females not in extra curriculars = 350 females in extra curriculars

350 + 90 males in extra curriculars = 440 total in extra curriculars

Circle A = 440

Circle B - overlap = 200 females not in extra curriculars

440 + 200 = 640

1000 - 640 = 370 students represented by the portion of the Venn diagram not in either circle
