When a number is added to itself the result is 49.​

Answer:

The answer is -(4/5)y - 3.

Step-by-step explanation:

The steps are :

[tex] \frac{1}{5} y - \frac{3}{5} y + 5 - \frac{2}{5} y - 8[/tex]

[tex] = ( \frac{1 - 3 - 2}{5} y) + (5 - 8)[/tex]

[tex] = - \frac{4}{5} y - 3[/tex]

Step-by-step explanation:

⅕y - ⅗y + 5 - ⅖y - 8

-0.8y-3

-4/5y-3

Answer:

x=1

Step-by-step explanation:

Add

16

to both sides of the equation.x=−15+16 Add −15 and 16.x=1

Answer:

Step-by-step explanation:

-16 + x = - 15

Add 16 to both sides

-16 + 16 + x  = -15 + 16

              x = 1

Answer:

72°

Step-by-step explanation:

Given

Zy = 108°

Zx = ?

We know

Zx + Zy = 180° {being supplementary angles }

Zx + 108° = 180°

Zx = 180° - 108°

Zx = 72°

Step-by-step explanation:

1st=8+4=12

2nd the answer is to the nearest 7.06

3rd =2+2³.7=2+13=15

4th=(36÷(4+5))+25=36÷9+25=4+25=29

5th=16÷16+8-3=1+8-3=9-3=6

6th=8-2.4=5.6

Step-by-step explanation:

Let's look at A(x) and see how it is different from f(x)

Therefore A(x) = f(x) - 8

Let's look at B(x) and see how it is different from f(x)

Therefore B(x) = f(x + 7)

Let's look at C(x) and see how it is different from f(x)

Therefore C(x) = f(x - 5) + 4

Let's look at D(x) and see how it is different from f(x)

Therefore D(x) = f(x - 12)

I took the test

Answer: About 7.3 units

Step-by-step explanation: I got it right

The length of the segment GH is given by the distance D = 7.3 units

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the first point be G ( -9 , -4 )

Let the second point be H ( -2 , -6 )

Let the length of the segment GH = D

Now , distance between G and H is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

On simplifying , we get

D = √ ( -9 - ( - 2 ) )² + ( -4 - ( -6 ) )²

D = √ ( -7 )² + ( 2 )²

On further simplification , we get

D = √ ( 49 + 4 )

D = √53

D = 7.28 ≈ 7.3 units

Hence , the distance is 7.3 units

Answer:

15% of 20 is 3, so 3 muffins were sold.

Step-by-step explanation:

To get this answer, multiply the percent by the total (15 x 20 = 300) and then divide the answer by 100. (300 / 100 = 3). Hope this helps :)

Answer:3

Step-by-step explanation:

0.15x20=3

0.15 is the percent of muffins, to find out a percentage over a number, you do the percentage dived by 100. Than, you multiply it by the number.

Answer:

Correct, good job!

Step-by-step explanation:

45% of $450:

$450 × 0.45 = $202.50

Add the 45% of $450 to $450

Answer:

There are 14 5-point questions and 10 3-point questions.

Step-by-step explanation:

Form 2 equations:

Let x= 5-point questions

Let y= 3-point questions

1.) x+y=24

2.) 5x+3y=100

Use substitution by reforming equation 1 in terms of x or y (I used y)

1.) y=24-x

Sooo, substitute this into the y in the 2nd equation:

5x+3(24-x)=100

5x+72-3x=100

2x=100-72

2x=28

x=14

Now that we have x, substitute this into the 1st equation to get y:

1.) y=24-x

y=24-14

y=10

In conclusion, there are 14 5-point questions and 10 3-point questions.

Answer:

There are 14 questions that are worth 5 points and there are 10 questions that are worth 3.

Step-by-step explanation:

14 x 5 = 70

10 x 3 = 30

70 + 30 = 100

14 + 10 = 24 questions total

Answer:

108º

Step-by-step explanation:

to find the sum of interior angles: ( n − 2 ) × 180 = x

x = 540º

n = # of interior angles

first, solve for n

(n - 2) • 180 = 540                        distribute to 180 to (n - 2)

180n - 360 = 540                         add 360 to both sides

180n = 900                                  divide both sides by 180

n = 5

to find measure of each angle:

540 ÷ 5 = 108º
