Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2?

Answers

3*1/6= 3/6 for three copies. 1/2 can equal half of any number. 3 is half of 6, so 3/6=1/2. 1/2 d 3/6 are equivalent fractions.

Is 2 x+6-x=1/3(3x+18) a one solution ,no solution ,or an infinite numbers of solutions

Answers

To determine this, the first thing we should do is simplify the expression. As usual, bring like terms to either side of the "=" and then simplify.
2x + 6 - x = 1/3 (3x + 18)
x + 6 = 1/3 (3x + 18)
x + 6 = 1/3 (3x) + 1/3(18)
x + 6 = x + 6

We can already see that both sides have the same expression "x+6". Now, if you try to simplify any further, you will get 0=0. That means that for any value of x, the expression will simplify to 0=0. Because 0=0 is a true statement, for every value of x, the expression will be true. Therefore, there are an infinite number of solutions.

Hope this helped!! :D

Answer:

n + p = m

Step-by-step explanation:

x(the unnamed angle) and m both equal 180

x + m = 180

x + n + p =180

180 = 180

x + m = x + n + p

m = n + p
