Answer:

GCF is 2.

Step-by-step explanation:

GCF is just the greatest factor of the whole number series.

Everything is divisible by 2 and not anything greater in this number series.

Therefore the GCF is 2.

Happy to help! Marking my answer as the Brainliest would really be aprreciated.

One way to do this is to consider what the average of these integers is. It would be 519/6, or 86.5. This means the six integers are "centered" around 86.5: they would be 84, 85, 86, 87, 88, and 89 (there are three numbers greater than 86.5 and three less than 86.5 in this list).

Answer:

Skiing costs $30 per hour and Boating costs $51 per hour.

Step-by-step explanation:

Let cost per hour of skiing be x and cost per hour of boating be y. Let's dissect the problem into 2 simultaneous equations.

"John paid $222 for four hours of skiing and two hours boating":

[tex]4x+2y=222[/tex]

"He paid $213 for two hours skiing and three hours boating":

[tex]2x+3y=213[/tex]

Now, if we solve for x in the 2nd equation and plug it in the 1st equation, we will have the value for y. Work shown below.

[tex]2x+3y=213\\2x=213-3y\\x=\frac{213-3y}{2}\\Equation 1: 4x+2y=222\\Substituting :\\4(\frac{213-3y}{2})+2y=222\\2(213-3y)+2y=222\\426-6y+2y=222\\426-222=6y-2y\\204=4y\\y=\frac{204}{4}=51[/tex]

Hence, y = 51

Now, substituting this y value into the 1st equation and solving for x will give us the value of x.

[tex]First Equation: 4x+2y=222\\4x+2(51)=222\\4x+102=222\\4x=222-102\\4x=120\\x=\frac{120}{4}=30[/tex]

Hence, skiing costs $30 per hour and boating costs $51 per hour.

Answer: B, 70 inches.

Step-by-step explanation:

Let's start slow and go shape by shape.

Based on the information we have, we know that the length for the rectangle is 8 inches by 7 inches. 8*7 = 56, so we have one of the answers.

Next, we do the triangle. Based on the information we have, we know that the triangle is 4 inches by 7 inches divided by 2. 4*7 = 28 [tex]\frac {28}{2} = 14[/tex]

Adding 14 and 56, we got the answer to be B, 70 inches.

I think it's 75 if wanting to add up to 180

The Y axis, would be when y = 0.

Point B is located on the Y -axis, so the coordinates would be the same.

For A and C the Y coordinate would remain the same and the X coordinate would be  the opposite ( from negative to positive).

A (-4,4) would become (4,4)

B (0,0) would stay the same so would be (0,0)

C (-5,-2) would become (5,-2)

The coordinates after reflection across the y-axis are:

- Point [tex]\( A' \): \((4, 4)\)[/tex]

- Point [tex]\( B' \): \((0, 0)\)[/tex]

- Point [tex]\( C' \): \((5, -2)\)[/tex]

Step 1: Identify the original coordinates of the points.

- Point [tex]\( A \)[/tex] is at [tex]\((-4, 4)\).[/tex]

- Point [tex]\( B \)[/tex] is at [tex]\((0, 0)\).[/tex]

- Point [tex]\( C \)[/tex] is at [tex]\((-5, -2)\).[/tex]

Step 2: Apply the reflection across the y-axis.

- Reflecting a point across the y-axis changes the sign of the x-coordinate, while the y-coordinate remains unchanged.

Step 3: Calculate the new coordinates.

For Point [tex]\( A \):[/tex]

- Original coordinates: [tex]\((-4, 4)\)[/tex]

- Reflected coordinates: [tex]\((4, 4)\)[/tex]

 - Negate the x-coordinate: [tex]\(-(-4) = 4\)[/tex]

 - Keep the y-coordinate the same: [tex]\(4\)[/tex]

For Point [tex]\( B \):[/tex]

- Original coordinates: [tex]\((0, 0)\)[/tex]

- Reflected coordinates: [tex]\((0, 0)\)[/tex]

 - Negate the x-coordinate: [tex]\(-0 = 0\)[/tex]

 - Keep the y-coordinate the same: [tex]\(0\)[/tex]

For Point [tex]\( C \):[/tex]

- Original coordinates: [tex]\((-5, -2)\)[/tex]

- Reflected coordinates: [tex]\((5, -2)\)[/tex]

 - Negate the x-coordinate: [tex]\(-(-5) = 5\)[/tex]

 - Keep the y-coordinate the same: [tex]\(-2\)[/tex]

Step 4: Write the coordinates of the reflected points.

- Point [tex]\( A' \): \((4, 4)\)[/tex]

- Point [tex]\( B' \): \((0, 0)\)[/tex]

- Point [tex]\( C' \): \((5, -2)\)[/tex]

So, the coordinates after reflection across the y-axis are:

- Point [tex]\( A' \): \((4, 4)\)[/tex]

- Point [tex]\( B' \): \((0, 0)\)[/tex]

- Point [tex]\( C' \): \((5, -2)\)[/tex]

Answer:

The answer is B.

Step-by-step explanation:

The architect wants to place a window in the center of the wall containing these two points: (3, 15) and (18, 2).

The coordinates of the center of the window are those of the mid-point betwween the two points: ( (3+18)/2, (15+2)/2 ) = (10.5, 8.5)

The answer is B.

Answer:

Step-by-step explanation:

ignore the text n focus on the coordinates (3, 15) and (18, 2) and that "the architect wants to place a window in the center of the wall containing these two points."

so the window will be right in the middle of (3, 15) and (18, 2).

take the average of the coordinates: (3+18)/2=10.5 n (15+2)/2=8.5

ans is B. (10.5,8.5)

Split the second term in 2x^2 + 7x + 3 into two terms

2x^2 + 6x + x + 3

Factor out the common terms in the first two terms, then in the last two terms;

2x(x + 3) + (x + 3)

Factor out the common term x + 3

= c: (2x + 1)(x + 3)

Answer:

y = 13x

Step-by-step explanation:

First we need to take the number miles the Johnson family drove and divide it to the number of gallons of gasoline used to find how many miles per gallon

Miles per gallon = 52/4

Miles per gallon = 13

Now that we know how many miles per gallon, let's make an equation to find how much they can travel on a full tank of 15 gallons.

Let y = number of miles traveled

Let x = number of gallons

y = 13x

Now let's see how much they can travel in 15 gallons.

y = 13x

y = 13(15)

y = 195 miles

So the Johnson family can drive 195 miles on a full tank of 15 gallons of gasoline.

Answer:

The value of b is, 8

Step-by-step explanation:

To determine the value of b:

Given:

[tex](152)_b = 0x6A[/tex]               ....[1]

Since, 0x6A represents the hexadecimal form.

To convert this hexadecimal form into decimal form:

[tex](6A)_{16}= (6 \times 16^1)+(A \times 16^0)=(6 \times 16)+(10 \times 1) =96+10 = 106[/tex]

⇒[tex]0x6A=106[/tex](decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

    |   1    |  5

        1

Then, the octal form we get, [tex](152)_8[/tex]

Substitute this in [1] we have;

[tex](152)_b = (152)_8[/tex]

On comparing both sides we have;

b = 8

Therefore, the value of b is, 8

take square root of 121, which is 11

so -12, 3, 10,

The values that satisfy the inequality x² > 121 are -12 and 13, as their squares are greater than 121.

The question asks which values satisfy the inequality x² > 121. To find the solutions, we need to consider when x² is greater than the square of 11, since 121 is 11². There are two cases:

Case 1: x is greater than 11.

Case 2: x is less than -11.

Now, evaluating the provided options:

A) -12: (-12)² = 144 which is greater than 121. Hence, -12 is a solution.

B) 3: (3)² = 9 which is not greater than 121. Therefore, 3 is not a solution.

C) 13: (13)² = 169 which is greater than 121. Thus, 13 is a solution.

D) 10: (10)² = 100 which is not greater than 121. So, 10 is not a solution.

Therefore, the correct answers that satisfy the given inequality are -12 and 13.

Final answer:

To solve the given system of equations using elimination, Heather's first step should be to manipulate the equations so that the coefficients of one of the variables (x or y) are the same in both equations. She can achieve this by multiplying the second equation by 3.

Explanation:

Heather has to solve the system of equations using elimination. The given equations are 3x+6y = 12 and x+5y = 10. The first step in solving these equations using the elimination method should be to manipulate the equations so that the coefficients of one variable are the same or additive inverses.

This allows one to eliminate that variable by adding or subtracting the equations. In this scenario, an efficient approach would be to multiply the second equation by 3, which makes the coefficients of x the same in both equations. Hence, the equations become 3x + 6y = 12 (unchanged) and 3(x + 5y) = 3(10), which simplifies to 3x + 15y = 30. This prepares the equations for the next step in the elimination process, which involves subtracting one equation from the other to eliminate the x variable.

The expression 9-(-5) simplifies to 9 + 5, which equals 14 when the numbers are added together.

To solve the expression 9-(-5), you should remember that subtracting a negative number is the same as adding its positive counterpart. Therefore, we change the subtraction of a negative number to the addition of a positive number. Following these steps, we have:

9 - (-5) = 9 + 5

Now, we simply add the numbers together:

9 + 5 = 14

So, the expression 9-(-5) equals 14.
