Answer:

2.5

Step-by-step explanation:

45/18 = 2.5

35/24 = 2.5

40/16 = 2.5

Answer:

x = - 18

Step-by-step explanation:

Given

- 7 + [tex]\frac{x}{3}[/tex] = - 13 ( add 7 to both sides )

[tex]\frac{x}{3}[/tex] = - 6 ( multiply both sides by 3 to clear the fraction )

x = - 18

Answer:

x = -32  or x = -18    Depends on how the equation is written

Step-by-step explanation:

-7 + x/3 = -13

Find the answer by solving for x.

If the equation is written like this:

[tex]\frac{-7+x}{3} = -13[/tex]           Multiply both sides by 3 and add 7 to both sides

x = -32

Or if the equation is written like this:

[tex]-7+\frac{x}{3} =-13[/tex]        Add 7 to both sides and then multiply by 3

x = -18

Answer:

  1. 2x +2y = 310; x -y = 55

  2. y = 50, x = 105

Step-by-step explanation:

Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...

  2x + 2y = 310

The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...

  x - y = 55

__

We can divide the first equation by 2, and subtract the second.

  1/2(2x +2y) -(x -y) = 1/2(310) -(55)

  2y = 100 . . . . . . . simplify

  y = 50 . . . . . . . . . divide by 2

  x -50 = 55   ⇒   x = 105 . . . . use the second equation to find x

The two numbers are 105 and 55.

Answer:

He will need 8.34 yards of fabric.

Step-by-step explanation:

Given that,

The length of the fabric, l = 2 2/3 yards = 8/3 yards

The width of the fabric, b = 1 1/2 yards = 3/2 yards

We need to find the piece of fabric Roberto needs. It is equal to the perimeter of the fabric such that,

[tex]P=2(l+b)\\\\P=2(\dfrac{8}{3}+\dfrac{3}{2})\\\\P=2\times \dfrac{25}{6}\\\\P=8.34\ \text{yards}[/tex]

So, he will need 8.34 yards of fabric.

Answer: k=1 which equals 1k.  

Step-by-step explanation:

k+0=k

k is really 1k

so the real equation is 1k+0=1k because 1k+0 means nothing really it's still 1k.  

Answer:

80

Step-by-step explanation:

30 = 100

24 = 80

6 x 5 = 30

6 x 4 = 24

5 = 20 because 5 x 8 = 80.

Answer:

80 persons haf fish and 152 persons had chicken

Step-by-step explanation:

Given data

let the number of persons that had fish be x and chicken be y

so

12x+9y=2544------------------1

x+y= 232------------------------2

from 2

x= 232-y

substitute the value of x in 1

12(232-y)+9y=2544

2784-12y+9y=2544

2784-3y=2544

3y= 2784-2544

3y=240

y= 240/3

y=80

put y= 80 in 2

x+80= 232

x= 232-80

x=152

Hence 80 persons haf fish and 152 persons had chicken

Answer:

50 deer in the forest.

Step-by-step explanation:

Since this is a ratio problem and we are given three values and a single unknown (total number of deer) we can use the Rule of three to solve for the variable. We do this by multiplying the diagonal values and then dividing by the last available value. That will give us the value of the variable which in this case would be represented as x.

20 deer <======>  6 tagged

x  deer  <======>  15 tagged

(20*15) / 6 = x

300 / 6 = 50 total deer

Based on these values we can estimate that there are a total of 50 deer in the forest.

Step-by-step explanation:

1 1/2 cups x 2 bread = 12

12 cups x 3 for 1/3 per recipe =36

Answer:

C.

Step-by-step explanation:

2 loaves of bread: 1 1/2 (flour per one loaf) * 2 (amt of loaves) = 3 (total flour used)

15 (total amt of flour) - 3 (flour used to bake bread) = 12 (remaining flour)

12 (remaining flour) / 1/3 (flour per muffin) = 36 (muffins able to be made)
