Aaron, Darren, Karen, Maren, and Sharon rode on a small train that has five cars that seat one person each. Maren sat in the last car. Aaron sat directly behind Sharon. Darren sat in one of the cars in front of Aaron. At least one person sat between Karen and Darren. Who sat in the middle car?

Answer:

Step-by-step explanation:

Answer: x=3, y-3

Step-by-step explanation:

I would use elimination

Multiply second equation by 2

2x + 2y = 12

2x + 3y = 15

Subtract both

-1y = -3, y = 3

Plug in 3 for y in any equation

x + 3 = 6, x = 3

Final answer: x = 3, y = 3

Enjoy!!

Answer:

The red car is faster compared to the blue car.

The red car is faster by 5.5 feet than the blue car.

Step-by-step explanation:

The objective is to find which car is  faster and by how much

Given that:

The blue car traveled 54 feet in 4 seconds; &

The red car traveled 38 feet in 2 seconds.

Let us determine the number of feet traveled in each second for both cases.

For the blue car:

In 1 second, the car will travel = 54/4 feet

In 1 second, the car will travel = 13.5 feet

For the red car:

In 1 second, the car will travel = 38/2 feet

In 1 second, the car will travel = 19 feet

Thus, the red car is faster compared to the blue car.

The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet

= 5.5 feet

Answer:

Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.

Step-by-step explanation:

I'll answer this question using the following illustration.

Let a fraction be:

[tex]\frac{1}{2}[/tex]

and another fraction

[tex]\frac{1}{4}[/tex]

Both numerators are 1. In other words, they are equal

When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater

This is so because:

[tex]\frac{1}{2} = 0.5[/tex]

[tex]\frac{1}{4} = 0.25[/tex]

By comparison

[tex]0.5 > 0.25[/tex]

This analysis can  be used for any fraction as long as they have the same numerator

Hence, option A answers the question

Answer:

A

Step-by-step explanation:

Answer:

(x + 1)² + (y - 6)² = 50

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

The radius is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)

r = [tex]\sqrt{(-6+1)^2+(1-6)^2}[/tex]

  = [tex]\sqrt{(-5)^2+(-5)^2}[/tex]

  = [tex]\sqrt{25+25}[/tex]

  = [tex]\sqrt{50}[/tex]

(h, k ) = (- 1, 6 ), then

(x - (- 1))² + (y - 6)² = ([tex]\sqrt{50}[/tex] )² , that is

(x + 1)² + (y - 6)² = 50 ← equation of circle

Answer:

No, the simplification is not done correctly. When multiplying

[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.

the correct answer is 12k-8

Step-by-step explanation:

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11[/tex]

No, the simplification is not done correctly. When multiplying

[tex]\frac{2}{3}\times-9[/tex] we should get -6 instead of -9.

Correcting the error:

[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 6 + 8k - 2\\=12k - 8[/tex]

So, the correct answer is 12k-8

Answer:

The answer is A

Step-by-step explanation:

Answer:

the Slope is -6/5  and y is (0,-3)

Step-by-step explanation:

we need to put this equation in y = mx + b  

6x - 5y = -15  u will subtract 6x from both sides

5y = -6x -15...divide both sides by 5

and then simplify

y = -6/5x - 3

and when u  graph its will be (0,-3)

ur slope(m) = -6/5 and ur y int (b) = -3

Answer:

A. x = 6

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + b^2 = 10^2

64 + b^2 = 100

b^2 = 100 - 64

b^2 = 36

√b^2 = √36

b = 6

Answer:

-1

Step-by-step explanation:

The formula is Y=mx+b and m is the slope while b is the y-intercept. So you plug in your numbers and i believe -1 is your y-intercept. :)
