Answer:

Step-by-step explanation:

2700x y = 3 * 3 * 3 * 2 * 2 * 5 * 2 * x * y

27y³ = 3 * 3 * 3 * y * y * y

GCF = 3*3*3*y

        = 27y

Answer: True

Step-by-step explanation:

Substitute -1 for x and 1 for y in the equation y = 4x + 5

(1) = 4(-1) + 5

1 = -4 + 5

1 = 1

Left side = right side

Therefore,  the point (–1, 1) satisfies the equation y = 4x + 5

Explanation:

rectangular prism volume = length * breath * height

Given:

using this formula:

[tex]\sf volume = length * breath * height[/tex]

[tex]\sf 1440 = 15 * 12 * height[/tex]

[tex]\sf height * 180 = 1440[/tex]

[tex]\sf height = \frac{1440}{180}[/tex]

Answer:

12possible dishes is the answer

Set up an equation :

4 x number - 7 = 45

Add 7 to both sides:

4 x number = 52

Divide both sides by 4:

Number = 13

Answer: 13

Answer:

13

Step-by-step explanation:

Because 4 times ? decreased by 7=45 then what times 4 =52 since it was decreased by 7 then 45+7=52.

We know it has to be more than 10 so what is 11 x 4=44  12 x 4=48  and 13 x 4=52 so 52 subtracted by 7=45 and there's your answer.

hope this helps have a great day:)

Answer:

Exact: 3,999,500,000

Estimate: 4,000,000,000

Step-by-step explanation:

(4)(10) = 40

(4 x 10)9 = 4,000,000,000

Notice that there are 9 zeros

_________________________________________

(5)(10) = 50

(5 x 10)5 = 500,000

Notice that there are 5 zeros

_________________________________________

4,000,000,000 - 50,000 = 3,999,500,000

Answer:

288

Step-by-step explanation:

Let x represent the smaller number then the larger number would be 120%x

We can use this to set up an equation:

[tex]x+120\%x=528[/tex]

Convert 120% to a fraction (any percentage is just that number over 100):

[tex]x+\frac{120}{100}x=528[/tex]

Simplify the fraction:

[tex]x+\frac{6}{5}x=528[/tex]

Add like terms:

[tex]\frac{5}{5}x+\frac{6}{5}x=528\\\frac{11}{5}x=528[/tex]

Multiply both sides by 5:

[tex]11x=2640[/tex]

Divide both sides by 11

[tex]x=240[/tex]

Therefore...

[tex]120\%*240=\frac{6}{5}(240)=\frac{1440}{5}=288[/tex]

The larger number is 288

Answer:

Step-by-step explanation:

Remark that exponential functions have horizontal asymptotes .

Scale : 2 inches = 39 miles

The length of the highway on the map is 9 inches -> the real length of it = 39 x 9 : 2 = 175.5 (miles)

There are 7 rest stops equally spaced => There are 7-1 = 6 equal distance between the rest stops

So, every rest stop is 175.5 : 6 = 29.25 miles apart from each other.

With a scale of 1 inch = 30 miles, each rest stop will be 29.25 : 30 = 0.975 inches apart from each other on the new map.

Step-by-step explanation:

To find the population density of any state:

We must divide the population number by the area

Thus Washington state's population density equals 7,705,281 / 71297.95

Which equals 108.1

Hope that helps!

Answer:

108.1 people per square mile

Step-by-step explanation:

The population density is people per area.

Take the population and divide by the area.

Washington state:

7705281/71297.95

108.07156

Rounding to the nearest tenth

108.1 people per square mile

Answer:

1. x = 23

2. y = 14

3. n = 17.5

4. x = 12

5. n = 11

Step-by-step explanation:

Complementary angles are equal to 90°

Vertical angles are congruent, which means they are equal to each other.

Supplementary angles are equal to 180°

1.

2x - 3 + 47 = 90

Step 1: Combine like terms (-3 + 47)

2x - 3 + 47 = 90

2x + 44 = 90

Step 2: Subtract 44 from both sides

2x + 44 - 44 = 90 - 44

2x = 46

Step 3: Divide by 2 on both sides

2x/2 = 46/2

Step 4: Simplify

x = 23

2.

5y + 12 = 82

Step 1: Subtract 12 from both sides

5y + 12 - 12 = 82 - 12

5y = 70

Step 2: Divide by 5 on both sides

5y/5 = 70/5

Step 3: Simplify

y = 14

3.

4n - 5 + 115 = 180

Step 1: Combine like terms (-5 + 115)

4n -5 + 115 = 180

4n + 110 = 180

Step 2: Subtract 110 from both sides

4n + 110 - 110 = 180 - 110

4n = 70

Step 3: Divide by 4 on both sides

4n/n = 70/4

Step 4: Simplify

n = 17.5

4.

Since m∠XYZ = 110°

3x + 2 + 72 = 110

Step 1: Combine like terms (2 + 72)

3x + 2 + 72 = 110

3x + 74 = 110

Step 2: Subtract 74 from both sides

3x + 74 - 74 = 110 - 74

3x = 36

Step 3: Divide by 3 on both sides

3x/3 = 36/3

Step 4: Simplify

x = 12

5.

5n + 35 = 90

Step 1: Subtract 35 from both sides

5n + 35 - 35 = 90 - 35

5n = 55

Step 2: Divide by 5 on both sides

5n/5 = 55/5

Step 3: Simplify

n = 11

5[tex]\sqrt{6.45}[/tex]

- Step one:

     -How many 5's go into 6? If you answered one, you're right.

5[tex]\sqrt{6.45}[/tex] = 1...

- Step two:

     - Now we have a remainder of one. When we bring down the 4, we have 14.

     - How many 5's can fit in 14? If you answered 2 with a remainder of 4, you're correct!

5[tex]\sqrt{6.45}[/tex] = 1.2......

- Step three:

      - Because we have one more digit left in 6.45, the five, we will bring it down. We now we have 45. How many 5's can fit in 45? If you answered 9, you're right!

5[tex]\sqrt{6.45}[/tex] = 1.29

So, this is how you do this division. I hope I helped you!
