fraction
Answer:
The answer is (4,-2)
Step-by-step explanation:
y=x-6
3x+2y=8
3x+2(x-6)=8
3x+2x-12=8 Combine like terms
3x+2x-12+12=8+12 add 12 to both sides then combine
5x=20→ x=4
then plug it in to y=x-6→y=4-6→y=-2
(5 * 1/3) * 3 = 5 * (1/3 * 3)
the associative property of multiplication allows us to regroup the numbers without changing the answer
(5 * 1/3) * 3 = 5/3 * 3 = 15/3 = 5
but by regrouping, it is much easier
5 * (1/3 * 3) = 5 * 1 = 5
another example..
(6 * 2/3) * 3/2 =
12/3 * 3/2 =
12/2 =
6
but by regrouping...
6 * (2/3 * 3/2) =
6 * 1=
6
