Answer:

First car consumed 25 gallons

Second car consumed 30 gallons

Step-by-step explanation:

Let x = first car gallons

     y = second car gallons

15x + 25y = 1125

x + y = 55

Let's use substitution method

Subtract both sides of the bottom equation by y

x + y = 55

  - y     - y

x = 55 - y

Plug in the new x into the top equation

15(55 - y) + 25y = 1125

825 - 15y + 25y = 1125

10y + 825 = 1125

Subtract 825 from both sides

10y + 825 = 1125

      - 825    - 825

10y = 300

Divide by sides by 10

10y/10 = 300/10

y = 30

The second car consumed 30 gallons

Plug in the new y into one of the original equations; let's use the bottom one

x + 30 = 55

  - 30   - 30

x = 25

The first car consumed 25 gallons

Answer:

0.5

Step-by-step explanation:

So tenth is at the 1st number from the "." so 0.1 So where the 1 is at. We then look at the thousandth spot and see if the number is over 5 if it is make it a 0 and make the next number to the left a +1, in this case 0.460, then make sure the hundredth place is over 5, as 6 is greater than 5 make the 6 a 0 and make the 4 a 5.

Step-by-step explanation:

You are being asked to draw the reflection of the triangle DKW.

As with a reflection in a mirror, the reflected object appears to be as far behind the mirror as the original object is in front of the mirror.

When you reflect a point across a line, the image is as far from the line on the other side as the original point is from the line. When the line of reflection is a vertical line, as here (x = 0 = y-axis), the y-coordinates are unchanged.

Points W and K are 2 units to the right of the y-axis. Their reflections will lie on the same horizontal line, but will be 2 units to the left of the y-axis.

Point D is 5 units to the right of the y-axis, so its reflection will be 5 units to the left.

Additional comment

The original triangle and its reflection are symmetrical about the line of reflection.

Answer:

Monday = 1,700

Tuesday = 1,900

Wednesday = 2,100

Step-by-step explanation:

i started by dividing the total (5700) by 3 (because there were 3 days)

5700 ÷ 3 = 1900

that gives us our middle number. from there, you subtract 200 to get the first day's number and add 200 to get the third day's number

1900 - 200 = 1700

1900 + 200 = 2100

Step-by-step explanation:

Looking at the graph, we can see that the y value of 7 corresponds to the x-value of -3. The y value is equivalent to the value f(x) holds. This means f(-3)=7 and x = -3.

Step-by-step explanation:

the answer is 3

Given that x° and 2x° are same-side interior angles, the value of x is: 60.

Recall:

x° and 2x° are same-side interior angles.

Therefore:

x° + 2x° = 180°

3x° = 180°

x = 180/3

x = 60

In summary, given that x° and 2x° are same-side interior angles, the value of x is: 60.

Answer:

if i'm correct the question is asking what's -8 x 3= -24

Step-by-step explanation:

Sorry if i'm wrong!  Hope this helps!

The answer is (x+4)² + y² = 16

x² + y² - 8x = 0

[reorder the terms]

x² - 8x + y² = 0

[to complete the square, add 16 to both sides]

x² - 8x + 16 + y² = 16

[write the expression as a product and 16 as an exponent]

x² - 2 × x × 4 + 4² + y² = 16

[using a² + 2ab + b² = (a + b)², factor the expression]

(x + 4)² + y² = 16

Since this equation can be written as

(x + p)² + (y - q)² = r², it represents a circle.

Answer:

The answer is 5.5

Answer:

Mean: 6

Median: 4.5

Mode: 4

Range: 13

Step-by-step explanation:

Answer:

mean = 6

median = 4.5

mode = 4

range = 13

Step-by-step explanation:

To find the mean, median, mode and range firstly place the numbers in ascending order.

2, 4, 7, 15, 7, 4, 5, 4

= 2, 4, 4, 4, 5, 7, 7, 15

(Mean is the average of all the data in a set.)

[tex] \\ \tt2, 4, 4, 4, 5, 7, 7, 15[/tex]

[tex] \\ \tt = \frac{2 + 4 + 4 + 4 + 5 + 7 + 7 + 15}{8} [/tex]

[tex] \\ \tt = \frac{48}{8} [/tex]

(Median is the middle number of the set.)

2, 4, 4, 4, 5, 7, 7, 15

median

= 4+5/2

= 9/2

= 4.5

(Mode is the number which appears multiple times.)

2, 4, 4, 4, 5, 7, 7, 15

mode = 4

(Range is the number which comes by subtracting the smallest number to the largest number.)

2, 4, 4, 4, 5, 7, 7, 15

Largest number = 15

Smallest number= 2

range

= 15-2

= 13

We can use the proportion. We already know

that Dixon is 6 ft tall and that his shadow is 9

ft long. Also we know that the shadow of his

sister is 6 ft long. 6: x = 9:6, or 6 / x=9/6.

After that we will cross multiply : 9 * x = 6 * 6,

9 x = 36, x = 36:9, x = 4. Answer: Ariadne
