First ten nonzero multiples of 2, 5, 6, 11, 20, 60

Answers

That depends on where you start, and in which direction you proceed.

If you start at zero and proceed in the positive direction, then you
encounter them as follows:

First ten non-zero multiples of  2 :
2,  4,  6,  8,  10, 12, 14, 16, 18,  20

First ten non-zero multiples of  5 :
5,  10,  15,  20,  25,  30,  35,  40,  45,  50

First ten non-zero multiples of  6 :
6,  12,  18,  24,  30,  36,  42,  48,  54,  60

First ten non-zero multiples of  11 :
11,  22,  33,  44,  55,  66,  77,  88,  99,  110

First ten non-zero multiples of  20 :
20,  40,  60,  80,  100,  120,  140,  160,  180,  200

First ten non-zero multiples of  60 :
60,  120,  180,  240,  300,  360,  420,  480,  540,  600

The correct answers are:

2, 4, 5, 8, 10, 12, 14, 16, 18, 20

5, 10, 15, 20, 25, 30, 35, 40, 45, 50

6, 12, 18, 24, 30, 36, 42, 48, 54, 60

11, 22, 33, 44, 55, 66, 77, 88, 99, 110

20, 40, 60, 80, 100, 120, 140, 160, 180, 200

60, 120, 180, 240, 300, 360, 420, 480, 540, 600

Explanation:

When finding the first non-zero multiples of a number, we count up by that number. For the twos, we keep adding 2 until we get the first ten terms. We follow a similar process for 5, adding 5 each time until we get the first ten terms.

What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!

Answers


                                              24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses:    24 + 3x = 3x + 3(6)

                                              24 + 3x = 3x + 18

Subtract  3x  from each side:       24  =  18

Look at that for a second.  Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."
