The sum of three numbers is 54. The third number is 6 more than the first. The second number is 2 times the third. What are the

77julia77 [94]

Answer:

9, 30, and 15.

Step-by-step explanation:

Let the three numbers be a, b, and c.

The sum of them is 54. So:

$a+b+c=54$

The third number is 6 more than the first. In other words, c=a+6.

The second number is twice the third. In other words, b=2c.

Let’s write the second number in terms of a. Since b=2c, this means that b=2(a+6).

Let’s substitute them into our equation. So:

$a+2(a+6)+(a+6)=54$

Solve for a. Distribute:

$a+2a+12+a+6=54$

Combine like terms:

$4a+18=54$

Subtract 18 from both sides:

$4a=36$

Hence, the value of a is:

$a=9$

So, the first number is 9.

The third number is 6 more than the first, so the third number is 15.

The second number is twice the third. So, the second number is 30.

Therefore, our numbers are:

9, 30, and 15.

Burka [1]

Answer=15X

$45/3 hours = $15/hour

(b) To see how much Louis makes per hour, simply plug in 1 for the hours value x:

y = 12(1 hours)

y = $12/hour

Thus Carl makes more than Louis.

In a history class, students take a weekly multiple choice quiz consisting of 6 questions, each with 4 possible answers. if a st

Mademuasel [1]

There are 24 possible answers, 6 are correct answers and 18 are incorrect answers. By use of the hypergeometric distribution the probabilities of each possible number of randomly selected correct answers can be found, as follows:
P(0) = 0.1379, P(1) = 0.3819, P(2) = 0.341, P(3) = 0.1213, P(4) = 0.017, P(5) = 0.0008, P(6) = 0.000007.
The expected or mean number of correct answers is found from:
$E(X)=0\times0.1379+1\times0.3819+2\times0.341+3\times0.1213+4\times0.017$ $+5\times0.0008+6\times0.000007=1.4998$
The answer is: 1.4998

The sum of the interior angles of a hexagon is equal to the sum of six consecutive integers. What is the measure of the smallest

Dmitrij [34]

The sum of the interior angles of a hexagon is equal to sum of six consecutive numbers. Hence let the smallest consecutive number be x. Then other five numbers are x+1, x+2, x+3,x+4 and x+5. Hence the measure of the smallest angle is 117.5 cm.

9. Five times a number is the same as the number added to five. What is the<br> number?

Alenkinab [10]

Let x be the number

5x = x + 5

subtract x from both sides

5x - x = 5

4x = 5

Divide both sides by 4

4x/4 = 5/4

x = 5/4

=======

Check:

5 * (5/4) = (5/4) + 5

25/4 = 1.25 + 5

6.25 = 6.25

Hope it helps . Note that I am a sixth grade student and I don’t know anything . I got help from somebody
