1 hr = 60 mins
10 hr = ... mins
600 mins + 39 mins = ... mins
639 mins + 24 sec=......mins
91 cm × 24 = ...
IDK what convention factors are tho...
Answer:35%
Step-by-step explanation:
-x + 2y = 6
6y = x + 18
Let's rewrite these equations.
-x + 2y = 6
6y - x = 18
If we multiply the second equation by -1 we can add both of them.
-x + 2y = 6
-6y + x = -18
Add:
-x + (-6y) + 2y + x = 6 + (-18)
2y - 6y + x - x = 6 - 18
-4y = -12
y = -12/-4
y = 3
Substitute y in the equation:
-x + 2y = 6
-x + 2.3 = 6
-x + 6 = 6
-x = 6 - 6
-x = 0
x = 0
Option B.
Answer:
Step-by-step explanation:
it is exponential decay
f(x)=a(1/2)^x
where a is the original volume and x is the time in minutes.
