three numbers are in an arithmetic progression. Their sum is 3 and the sum of their squares is 11. what are the three numbers
Vlad [161]

The three numbers are 12, 18 and 24

Arithmetic progression

Let the 3 number in arithmetic progression be:

a-d, d, a+d ...

If their sum is 3, then;

a-d+d+a+d = 3

2a + d = 3 ........... 1

If the sum of their squares is 11, then;

(a-d)² + d² + (a+d)² = 11

a²-2ad+d²+d²+a²+2ad+d²  11

2a²+3d² = 11 ....... 2

Solving the equations simultaneously, d = 6 and a = 12

First-term = 12

second term = 18

Thirs term = 24

Hence the three numbers are 12, 18 and 24

Hope this helps you!!!!!! :D

What is the solution to x=1/2y-3 and y=2x+6
Tom [10]

Answer:

infinite solutions

Step-by-step explanation:

Multiply the first equation by 2 so we don't have fractions.

x = 1/2y - 3 becomes 2x = y - 6

Now substitute the second equation into the y-value of the new equation

2x = (2x + 6) - 6

2x = 2x

x can equal anything. this means there are infinite solutions

Below is a piece of a local pizza place menu where Jacob works.
Hatshy [7]

1)

16.90 is about $17

$17 * 3 = 51

6.99 is about $7

7 * 4 = 28

28 + 51 = 79

This is not reasonable because it costs $79, which is more than $75.

7 * 3 = 21

21 + 51 = 72

The customer has enough for 3 supreme pizzas and 3 dessert pizzas.

2)

16.90 is about 17

5.99 is about 6

17 + 6 = 23

23 - 5 = 18

This is reasonable.

3)

14.85 is about 15

6.99 is about 7

15 + 7 = 22

22/100 = 0.22

0.22 * 22 = 4.84

This is reasonable.

4)

16.90 is about 17

14.85 is about 15

5.99 is about 6

6.99 is about 7

17 * 5 = 85

15 * 5 = 75

6 * 5 = 30

7 * 5 = 35

85 + 75 + 30 + 35 = 225

This is reasonable

5)

14.85 + 1.39(4) = 20

1.39 * 4 = 5.56

14.85 + 5.56 = 20.41

This is not reasonable because the total is more then $20.
