From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
Answer:
2/6
Step-by-step explanation:
there is only two fives with two dice, the dice only have six sides therefore the chances would be two out of five

Answer:
(b) (1, 1/6)
Step-by-step explanation:
The "unit rate" is always the y-value for x=1 when the relationship is proportional (as it is here).
That point is not specifically shown on the graph. It would be (1, 1/6).
If it has 3 sides then it's a triangle.
Using the formula
where
and a=5 b=5 c=8
∴
