Adults = 9
Children = 2
Let x be the number of adults.
11-x is the number of children.
22x + 15(11-x) = 228
22x + 165 - 15x = 228
22x - 15x = 228 - 165
7x = 63
7x / 7 = 63 / 7
x = 9 number of adults.
11 - x = 11 - 9 = 2 number of children.
To check:
22x + 15(11-x) = 228
22(9) + 15(11-9) = 228
198 + 30 = 228
228 = 228
(not my answer btw)
-20/48 x 6 =
![\frac{-20}{48}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-20%7D%7B48%7D%20)
x
![\frac{6}{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B1%7D%20)
I would cancel out the 6 in the numerator and the 48 in the denominator
Now I have <u />
![\frac{-20}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-20%7D%7B8%7D%20)
or <u />
![\frac{-5}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-5%7D%7B2%7D%20)
reduced.
-5 ÷ 2 = -2 1/2 and that is the answer in simplest form
The correct answer to the question that is being asked and presented above would be 'composite'. If there are two or more basic geometric figures combined, they form what is called a 'composite' figure.
