Find three consecutive even intergers whose sum is 72

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
3 0

Answer:

The three numbers are: 22, 24, 26

Consecutive even numbers don't have every number, just the even ones.  So, for example, 40, 42, 44 are three consecutive even numbers.

The sum comes from addition.

Let any of the numbers be x (but, remember that the equations change based on which number you pick):

   Sum = (x) + (x+2) + (x+4) = 72

    3x + 6 = 72              (collect like terms)

    3x =  66                 (subtract 6 from both sides)

    x = 22         (I let x=first number)

What is the equation of the line that is parallel to the given line and passes theought the point (12, -2)
Nesterboy [21]

Answer:

<u>Option </u><u>D</u> (y = 5/6x -12).

Step-by-step explanation:

Hey there!

The equation of the line which passes through the point (12,-2) is (y+2) = m2(x-12)………(i) [Using one point formula].

According to the question, the first line passes through point (12,6) and (0,-4).

So,

slope(m1) =  \frac{y2 - y1}{x2 - x1}

or \: m1 =  \frac{ - 4 - 6}{0 - 12}

or \: m1 =   \frac{5}{6}

Therefore, the slope of the line is 5/6.

Now as per the condition of parallel lines, m1 =m2 = 5/6.

So, keeping the value of m2 in equation (i), we get;

(y+2) = 5/6(x-12)

y + 2 =  \frac{5}{6} x - 10

or, y = 5/6x - 12.

Therefore, the required equation is y = 5/6 X - 12.

Can some one help me i need help it is 6x-1/5=3/1 but its not hole numbers
baherus [9]
X = 8/15
6x - 1/5 = 3/1
6x - 1/5 = 3
6x = 3 + 1/5
6x = 15 + 1 over 5 
6x = 16/5
x = 16/30
Then, you simplify. 
x = 8/15

Name two different numbers that round to 30 when rounded to the nearest ten
andrew11 [14]

For this case we have the following definition:

tens place: number of two digits whose absolute value is greater than zero.

Then, we have the following rounding rule:

If the previous number is greater than or equal to five, the next number increases by one unit.

We then have the following numbers rounded to 30 when rounded to the nearest ten:

26: twenty-six

27: twenty-seven

Answer:

two different numbers that round to 30 when rounded to the nearest ten are:

26: twenty-six

27: twenty-seven
