Kim Kardashian has 4 children. North West is 5 years older than Chicago
West. Psalm West is a year younger than Chicago West. Saint is twice as
old as Chicago. If the sum of their ages is 14, how old is North West? Write an equation

Answer:

It is hard to tell from this image, but I believe the word you are looking for is Integer. Integers are any positive or negative whole number.

Answer:

180-(25x+5)=9x+5

180-25x-5=9x+5

-34x=-170

x=5

Answer:

y=-1/2x+2

the y-intercept is at 2 and the slope is -1/2

meaning the y coordinates with move down 1 while the x coordinates will move 2 in a positive (right) direction

Answer:

50%

Step-by-step explanation:

Answer:

8.69%.

Step-by-step explanation:

Estimated value = $250

Actual value = $230

We need to find the percent error. It can be calculated as follows :

[tex]\%=\dfrac{|\text{estimated-actual}|}{\text{actual}}\times 100\\\\=\dfrac{250-230}{230}\times 100\\\\=8.69\%[/tex]

So, the percent error is 8.69%.

Step-by-step explanation:

1/625×15625

We wil add power 2 as shown in the bracket

It will be 1/390625×244140625=625

Answer: 2x-3y=4

Answer:

I guess that the question should say:

You need 3 scoops of powder lemonade mix to make two quarts of lemonade. How many scoops of powder lemonade mix are needed to make 3 gallons?

3 gallons = 12 quarts

if you need 3 scoops top make 2 quarts, then you will need (12/2) x 3 = 18 scoops of lemonade powder mix to make 3 gallons of lemonade.

The initial value of f(x) is 0.

The range of values for f(x) is 0 ≤ f(x) ≤ 6.

*Hint: You can use a table to do this one and plug in -4, -3, -2, and -1 in for x in the rule for the function of f(x), and -4 is your initial x-value. The answer from the first line is the same answer for the other blank.

Answer:

20 feet long

Step-by-step explanation:

To solve this you need to use the Pythagorean theorum, [tex]a^2+b^2=c^2[/tex], where c is the length of rope needed and A and B are the side lengths. Think of it like a right triangle.

So, the equation is

[tex]12^2+16^2=c^2[/tex]

Which is then

[tex]144+256=c^2[/tex]

[tex]c^2=400[/tex]

And the possible values of c are 20 and -20.

From here we know the answer cannot be -20 because you cannot have a negatively long length of rope, so the answer must be 20 feet.

Answer:

20 feet

Step-by-step explanation:

Use Pythagoras's theorem.

[tex]A^{2}+B^{2} =C^{2} \\12^{2} +16^{2}= C^{2} \\400 = C^{2} \\\sqrt{400}= \sqrt{C^{2}\\\\[/tex]

20 = C

You can not reduce it further only in decimals

Answer:

y = 1/4 x - 31/4

Step-by-step explanation:

Slope (m) = 1/4

Point A (-1, -8)

y = mx + b

-8 = 1/4 (-1) + b

-8 + 1/4 = b

b = -32/4 + 1/4

b = -31/4

y = mx + b <-- this is a linear equation, continuing line, so there are infinite values for x and y. Therefore we don't have to plug the values of x and y in

y = 1/4 x + - 31/4

y = 1/4 x - 31/4

Answer:

24

Step-by-step explanation:

Answer:

1cm=50km

Step-by-step explanation:

325 divided by 6.5 is 50, so 1 centimeter equals 50 kilometers on the map scale.

Answer:

20:12

Step-by-step explanation:

[tex]5:3 = \frac{5}{3} \\ 20:12 = \frac{20}{12} = \frac{5}{3} \\ = 5:3[/tex]

Answer:

Step-by-step explanation:

20divided by 4is 5

12 divided by 4 is 3

Answer:

x = 0

Step-by-step explanation:

2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing

2(x+7) would be 2x+14

4(2x+8) would be 8x+32

2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms

2x and 2x can be combined on the left side

x and 8x can be combined on the right side

4x + 14 + 20 - 2 = x + 8x + 32

4x + 32 = 9x + 32 you can now solve this equation

start by subtracting 4x on both sides

32 = 5x +32 now subtract 32 on both sides

0 = 5x so x = 0

Answer:

x = 0

2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing

2(x+7) would be 2x+14

4(2x+8) would be 8x+32

2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms

2x and 2x can be combined on the left side

x and 8x can be combined on the right side

4x + 14 + 20 - 2 = x + 8x + 32

4x + 32 = 9x + 32 you can now solve this equation

start by subtracting 4x on both sides

32 = 5x +32 now subtract 32 on both sides

0 = 5x so x = 0

Answer:

Variables help show the numbers and equation show the numbers

Step-by-step explanation:

Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Step-by-step explanation:

Hope this helps.. ;)

Step-by-step explanation:

Does that make sense to u??

if the equation is y+=1/2 (x-3) the slope is wrong.  the slope is actually 6. that was the error that Sydney made. i hope this help some of my people out:)

Answer:

37.5 units

Step-by-step explanation:

I assume that there is condition: BC║DE . If so, then ΔABC ~ ΔADE ⇒ that corresponding sides are proportional.

[tex]\frac{BC}{DE}[/tex] = [tex]\frac{AC}{AE}[/tex]

AC = 30 + 20 = 50

[tex]\frac{x}{15}[/tex] = [tex]\frac{50}{20}[/tex] ⇒ x = [tex]\frac{15*50}{20}[/tex] = 37.5 units

Answer:

10 and 12

Step-by-step explanation:

Let the smallest number = 2x

Then the larger number is 2x + 2

2x + 2x + 2 = 2x + 2 + 10                     Subtract 2x + 2 from both sides

2x = 10                                                  Divide by 2

x = 5

The smaller number is 2x = 2 * 5 = 10

The larger number is 2x + 2 = 12
