There are infinity of fractions equal to 1/2, it just means half of a number, so for example, 3/6, 4/8, 5/10, 6/12 are all equal to 1/2 and so on
Answer:
(3x - y)(3x + y)
Step-by-step explanation:
Both 9x^2 and y^2 are perfects squares.
The rule for factoring perfect squares is a^2 - b^2 = (a - b)(a + b).
Here, factoring (3x)^2 - y^2 results in (3x - y)(3x + y).
Not really sure of this one but i think it's like this-
2/10 (money for story) + 3/10 (26.80 dollars to brother)= 1/2 of his money
3/10x=26.80 268=3x ; x= 89.33333....
89.33 X 5/10= answer
money left= (roughly) 44.67
