Five less than twice a number is equal to one half the difference of three times the number and 13. find the number.

That number would be -3.

For the purpose of solving this, let that number be x. Now write out the front side of the equation:

2x (twice a number) - 5 (five less than)

2x - 5

Now write out the other side

1/2 (one half of) (3x - 13) (The difference of 3 times the number and 13)

1/2(3x - 13)

Now set the two sides equal to each other and solve

2x - 5 = 1/2(3x - 13) > multiply both sides by 2

4x - 10 = 3x - 13 > subtract 3x from both sides

x - 10 = -13 > add 10 to both sides

x = -3

the answer will be the last one

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
