** 3x - x -7 = 3

2x = 10

x = 5

** <span>6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = </span> $\frac{6}{17}$

** <span>7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** </span><span>8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = </span> $\frac{28}{23}$

** <span>9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

A paper clip is just over 4 cm long. How many paper clips like this can be made from a straight piece of wire 10 meters long?

bixtya [17]

Answer:

25 Paper Clips

Step-by-step explanation:

100cm is equal to 1 meter. So to find the answer you would need to take the whole of the centimeter (100) and divide that by the paper clips length (4).

100/4 = 25

So, to form a straight line 10 meters long you would need 25 paper clips each 4cm long.
