Answer:three consecutive odd numbers are 25; 27; 29

suppose: the smallest number is x ( x > 0),(x ∈ N)

because 3 numbers are three consecutive odd numbers

=> The next 2 terms respectively are x + 2; x + 4

have: The sum of three consecutive odd numbers is 81

=> x + x + 2 + x+ 4 = 81

⇔ 3x + 6 = 81

⇔ 3x = 81 - 6

⇔ 3x = 75

⇔ x = 25

=>  three consecutive odd numbers are 25; 27; 29

Answer:

The 3 odd, consecutive numbers are 25, 27, and 29.

Step-by-step explanation:

When you add these 3 numbers you will get 81.

25 + 27 = 52

52 + 29 = 81

Therefore, 25 + 27 + 29 = 81

Hope this helps!!

Y=8x-4 find y and x intercept
dlinn [17]

Answer:

<h3>The x intercept is 1/2</h3><h3>The y intercept is - 4</h3>

Step-by-step explanation:

y = 8x - 4

First to find the y intercept let x = 0

Substitute the value of x into the equation

That's

y = 8(0) - 4

y = - 4

<h3>The y intercept is - 4</h3>

To find the x intercept let y = 0

Substitute the value of y into the equation

that's

8x - 4 = 0

8x = 4

Divide both sides by 8

x = 1/2

<h3>The x intercept is 1/2</h3>

Hope this helps you

Sladkaya [172]

Answer:

  a. 2116 miles

  b. 105.8 gallons

  c. $305.76

  d. cost per gallon = total cost / number of gallons = total cost/105.8

Step-by-step explanation:

<h3>a. </h3>

The round-trip distance is the sum of the distances there and back. It is double the one-way distance.

  round-trip distance = 2 × one-way distance

  round-trip distance = 2 × 1058 miles = 2116 miles

__

<h3>b.</h3>

The gas used will be the distance divided by miles per gallon.

  gas used = round-trip distance / miles-per-gallon

  gas used = (2116 mi)/(20 mi/gal) = 105.8 gal

__

<h3>c.</h3>

The cost of gas will be the product of cost per gallon and number of gallons.

  cost of gas = cost-per-gallon × gallons

  cost of gas = $2.89/gal × 105.8 gal = $305.762 ≈ $305.76

__

<h3>d.</h3>

The relation used in the previous step can be used to find the cost per gallon. Divide that equation by gallons to get ...

  (cost of gas)/gallons = cost-per-gallon

For the same trip, the number of gallons is 105.8, so the equation becomes ...

  cost-per-gallon = (cost of gas)/105.8

What is an equation of the line that passes through point (5,-8) and is parallel to the line x+y=7
Igoryamba

Answer:

The line given is equal to y=-x+7 (Through rearranging)

To find the new line, we substitute the given coordinates (5,8) in the equation without the given y-intersect (+7):

-8=-5+c

c=-3

The line parallel to x+y=7 that passes through the point (5,-8) is y=-x-3
