Answer:
33.33 mL of 50%
66.67 of 80%
Step-by-step explanation:
Let x = quantity of 50% methane.
Then,
0.50x + 0.80(100 - x) = 100 × 0.70
⇒ 0.50 x + 80 - 0.80 x = 70
⇒ -0.30 x = 70 - 80
⇒ -0.30 x = -10
⇒
⇒ x = 33.33 mL of 50%
and, 100 - 33.33 = 66.67 of 80%
Answer:
[see below]
Step-by-step explanation:
Find two points that would satisfy the equation.
When x = 1:
One point would be (1, 3).
When x = 2:
Another point would be (2, 6).
Graph the points (1,3) and (2,6) and draw a line crossing through them.
