The sum of three consecutive integers is -54. What are the integers?

Mathematics
1 answer:
tresset_1 [31]2 years ago
5 0

Answer:

-19, -18, -17

Step-by-step explanation:

1. To find the sum of three consecutive integers, we can use the formula x + x + 1 + x + 2, where x = first term. As you can see from the formula, + 1 is the next term, and + 2 is the following term after that.

2. (Solving)

Step 1: Combine like terms.

  • (x + x + x) + (1+2) = -54
  • 3x + 3 = -54

Step 2: Subtract 3 from both sides.

  • 3x + 3 - 3 = -54 - 3
  • 3x = -57

Step 3: Divide both sides by 3.

  • \frac{3x}{3} = \frac{-57}{3}
  • x = -19

3. Now that we know our first term is -19, let's apply it to x + x + 1 + x + 2.

  • (-19) + (-19+1) + (-19+2)
  • -19 + (-18) + (-17)

4. Okay, so we got that the integers are -19, -18, and -17. Let's check if these numbers sum to -54.

  • -19 - 18 - 17
  • -37 -17
  • -54

Therefore, the integers are -19, -18, and -17.

Write in point-slope form an equation of the line that passes through the
QveST [7]

Answer:

y+6 = - 5(x-4)

Step-by-step explanation:

With the given information, use the point-slope formula y-y_1 = m (x-x_1) to write the equation of the line. Substitute values for the m, x_1, and y_1 to find the answer.

m represents the slope, so substitute -5 in its place. The x_1 and y_1 represent the x and y values of one point the line intersects, so substitute 4 for x_1 and -6 for y_1. This gives the following equation:

y+6 = - 5(x-4)

LOOK HOW MANY POINTS!!! PLEASE HELP ASAP A cell phone company tests 75 cell phones and finds that 3 of them have defects. Out of
kozerog [31]

Answer:

Out of 450 phones 18 of them will have a defect.

Step-by-step explanation:

As we know that out of 75 phones 3 of them will have a defect, this means that we are able to calculate how many defects there will be from 450 phones. You can do this by first dividing 450 by 75, this gives you 6. This means that 75 will go into 450 6 times.

From this we are able to work out the number that will have defects. This is because we know that 75 goes into 450 6 times and that for each 75 phones there will be 3 defects. So to work out the number of phones out of 450 that would be defects you would simply multiply 3 by 6, this gives you 18. This shows that out of 450 phones 18 of them will have a defect.

1) Divide 450 by 75.

450/75=6

2) Multiply 6 by 3.

6*3=18

Roger is x centimeters tall and Olivia is y centimeters tall. Their oldest sister, Isabella, is 25 centimeters shorter than the
sukhopar [10]

Answer:

<h2><em>[2(x+y)-25]cm</em></h2>

Step-by-step explanation:

Let the height of their oldest sister isabella be z centimeters. Roger is x centimeters tall and Olivia is y centimeters tall.

If their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia's height, this can be expressed as shown;

First let us get the sum of Roger and Olivia's height;

The sum of Roger and Olivia's height = (x+y)cm

The double of the sum of their ages = 2* (x+y)cm = 2(x+y)cm

Now if Isabella, is 25 centimeters shorter than the double of the sum of their ages, the expression will be [2(x+y)-25]

<em>Since the height of isabella is z, the expression that model isabella's height will be expressed as z =[2(x+y)-25]cm</em>
