To solve for three consecutive integers whose sum is 9, we can express the integers as n, n + 1, and n + 2. Using the equation n + (n + 1) + (n + 2) = 9, we find that n = 2. Therefore, the three consecutive integers are 2, 3, and 4.

To solve for three consecutive integers whose sum is 9, we can start by expressing the integers in terms of a variable. Let's use the variable n to represent the first integer.

The second integer would then be n + 1, and the third integer would be n + 2.

The sum of these three integers is given as 9, so we can write the equation n + (n + 1) + (n + 2) = 9.

Simplifying the equation by combining like terms, we get 3n + 3 = 9. Subtracting 3 from both sides, we have 3n = 6. Finally, dividing both sides by 3, we find that n = 2.

Therefore, the three consecutive integers are 2, 3, and 4.

Answer:

Out of all four, your answer would be the second choice: Y=0.4X.

Step-by-step explanation:

In order to get the answer, all you have to do this divide any y value you find on the line by the any x-value (as long as they're connected).

In this case, I decided to divide 2 by 5.

2/5 = 0.4.

You can also divide 4 by 10 and 6/15. You'll always get 0.4 as your answer.

P.S. I wish you good luck with the rest of your assignment!!

The expression (2x + 17) represents how much money Gary will have left over after purchasing two pairs of jeans.

To find out how much money Gary will have left over after purchasing two pairs of jeans, we need to subtract the cost of the jeans from the total amount Gary has.

Total amount Gary has = (10x + 7)

Cost of two pairs of jeans = (2(4x - 5))

Now, subtract the cost of jeans from the total amount:

Leftover money = (10x + 7) - 2(4x - 5)

Let's simplify this expression:

Leftover money} = 10x + 7 - (8x - 10)

Leftover money} = 10x + 7 - 8x + 10

Leftover money} = 2x + 17

So, the expression (2x + 17) represents how much money Gary will have left over after purchasing two pairs of jeans.

Answer: 12

Step-by-step explanation: (s-2)(180)=1800, s-2=10, s=12

Using the formula for the sum of the interior angles of a polygon, we can determine that a polygon with an interior angle sum of 1800 degrees has 12 sides.

To determine the number of sides a polygon has based on its interior angle sum, we can use the formula for the sum of the interior angles of a polygon, which is (n - 2) times 180 degrees, where n is the number of sides of the polygon. Given that the sum of the interior angles is 1800 degrees, we can set up the equation n - 2 = 1800 / 180, which simplifies to n - 2 = 10. Solving for n gives us n = 12, so the polygon must have 12 sides.

Answer:

Nina is 25, Sam is 15

Step-by-step explanation:

5 years ago, Nina was 2S, and Sam was S.

In 5 years, she will be 1.5S and Sam is S.

In a span of 10 years, she will be 0.5S less.

20, 10 5 years ago

Currently, 25 and 15 years.

30 and 20 years in 5 years.

20*1.5=30

By solving from an expression Nina is currently 25 years old and Sam is currently 15 years old.

In mathematics, an expression is a combination of one or more numbers, variables, constants, and operators, which when evaluated, produce a value. Expressions can include mathematical symbols such as addition, subtraction, multiplication, division, exponents, roots, logarithms, and trigonometric functions.

Let's start by assigning variables to their current ages. Let N be Nina's current age and S be Sam's current age.

We know from the first sentence that 5 years ago, Nina was twice as old as Sam. So we can set up an equation based on that:

N - 5 = 2(S - 5)

Expanding the right side:

N - 5 = 2S - 10

N = 2S - 5

Now we can use the second sentence, which tells us that in 5 years Nina will be 1.5 times as old as Sam.

N + 5 = 1.5(S + 5)

Expanding the right side:

N + 5 = 1.5S + 7.5

N = 1.5S + 2.5

We have two equations, one for N in terms of S and one for N in terms of S. We can set them equal to each other:

2S - 5 = 1.5S + 2.5

Solving for S:

0.5S = 7.5

S = 15

So Sam is currently 15 years old. We can use either equation to find Nina's age:

N = 2S - 5

N = 2(15) - 5

N = 25

So Nina is currently 25 years old.

Answer:

A) 0.072 = 7.2%

B) 8.3333 at-bats (8 to 9 at-bats)

Step-by-step explanation:

A)

If the chance of hitting a home run is 0.12, the chance of not hitting a home run is 1 - 0.12 = 0.88.

To find the probability of the next home run being in the fifth strike, we need the four other strikes to not be a home run, so the probability is:

P = (0.88)^4 * 0.12 = 0.072 = 7.2%

B)

To find the expected number of at-bats until the next home run, we just need to divide 100% by the probability of hitting a home run (0.12 = 12%):

100/12 = 8.3333

So the expected number is 8 to 9 at-bats

Because these angles are the same, we can make an equation, 5x-5=3x+13.

2x - 18  =   2 • (x - 9)

Solve :    2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solve  :    x-9 = 0  

Add  9  to both sides of the equation :  

x = 9

Replace x with 9 in this equation,  3(9) + 13

Rounded to the nearest hundredth, the volume of the sphere with a radius of 4 ft is approximately 267.95 cubic feet.

The formula for the volume V of a sphere is given by:

[tex]\[V = \frac{4}{3} \pi r^3\][/tex]

Given:

Radius r = 4 ft

Let's calculate the volume using the given radius:

[tex]\[V = \frac{4}{3} \times 3.14 \times 4^3\][/tex]

[tex]\[V = \frac{4}{3} \times 3.14 \times 64\][/tex]
