Answer:
x = 3
Step-by-step explanation:
2x - y = 4
y = -2x + 8
-y = -2x + 4
y = -2x + 8
0 = -4x + 12
-4x = -12
x = 3
Answer:
2/3 1/5 6/8
Step-by-step explanation:
1/3=2/6
So he ate 2/6ths of the pizza and now there is 4/6ths left.
He took 1/6ths with him for lunch so 4/6-1/6=3/6
You can simplify 3/6 to 1/2
He was 1/2 of the pizza left.
The pattern is dividing by 2.
512, 256, 128, 64
512/2 = 256, 256/2 = 128, 128/2 = 64
64/2 = 32, 32/2 = 16, 16/2 = 8, 8/2 = 4, 4/2 = 2, ...
