Answer:

First, you have to distribute the 1/3. To do this, you can either multiply everything in the parentheses by 1/3 or you can divide it all by 3. I will use the division method, so 24x/3 is 8x and -9/3 is -3, so now the expres

my yard is 32 ft long by 20 ft wide what is the area of my yard

Answers

In order to find Area you need to know the formula
Area=Length*Width
In this case we know that the Length is 32ft and the Width is 20 ft.
A=32*20
A=640ft^2
my yard is 32 ft long by 20 ft wide what is the area of my yard
area = length x width
so you do 32 x 20 which is 640.
640 is your area.

8/7 = 12/k solve for k

Answers

Answer:

k = 10.5

Step-by-step explanation:

8/7 = 12/k

Using cross products

8k = 7*12

8k = 84

Divide each side by 8

8k/8 = 84/8

k = 10.5

Answer:

k= 10.5

Step-by-step explanation:

We can solve this by using cross multiplication

We multiply the values across from each other

8k=7(12)

Then we multiply 7 and 12, and then divide by 8

8k=84

k= 10.5

In 56 years, Kevin will be 9 times as old as he is now

How old is Kevin now?

Answers

Answer:

correct answer is 7 years

Step-by-step explanation:

A+56=9(A)

56+9A

A=7

he will be 7 years old he is pretty old

Answer:

Kevin is 7 years old right now.

Step-by-step explanation:

Let x be Kevin's age right now, that's what we're trying to find.

In 56 years, he'll be 9 times older than he is now, so we can say:

x + 56 = 9x

Now we can get the x values on the right side of the equation so that:

56 = 8x

Now solve for x and you have his current age which is 7.

Can yall give me 4 examples of rules of exponents with answers pls?

Answers

Answer and Step-by-step explanation:

When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:

\(a^{x} * a^{y} = a^{x+y}\)

When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:

\(a^{x} / a^{y} = a^{x-y}\)

When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:

\((a^{x)^{y} } = a^{xy}\)

When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:

\((ab)^{x} = a^{x} b^{x}\)

Answer:

W = 8.2 cm

Step-by-step explanation:

The perimeter formula is P = 2W + 2L and here the perimeter is 65.6 cm.

Thus, 65.6 cm = 2W + 2L.  Substituting 3W for L, we get

          65.6 cm = 2W + 2(3W) = 8W.

Solving for W by dividing both sides by 8, we get W = 65.6 cm / 8, or

W = 8.2 cm

W=8.2 cm. Trust me I have my sources.

Answers

Hans spent 9% on fruit


Answer: 70%

Step-by-step explanation:

The total answers count 30 - it's 100%, so to get a 1% value, divide 30 by 100 to get 0.30. Next, calculate the percentage of 21: divide 21 by 1% value (0.30), and you get 70.00%

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

Step-by-step explanation:

x needs to be equal or less than 3. It doesn't say that x cannot be negative so any number 3 and below is fine.

Not solutions would be any number above 3 in value

The three solutions for the inequality are 1, 2, and 3.

And, the three numbers that are not solutions are 4, 5, and 6.

Used the concept of inequality that states,

A relation by which we can compare two or more mathematical expressions is called an inequality.

Given that,

The inequality is,

x ≤ 3

Now from the given inequality x ≤ 3,

The solution of the inequality is a number that is less or equal to 3.

Hence the possible three solutions for the inequality are,

x = 1, 2, 3

And, the three numbers that are not solutions are,

4, 5, and 6.
