Answer:
1:3
Step-by-step explanation:
<h2>Answer:</h2>
5x + 7y = 17 ....(1)
x + 4y = 19 .....(2)
<u>From equation 2</u>
x + 4y = 19
x = 19 - 4y
<u>Putting the value of x in Equation (1)</u>
5(19 - 4y) + 7y = 17
95 - 20y + 7y = 17
- 20y + 7y = 17 - 95
-13y = -78
y = 
y = 6
<u>Now, putting the value of y in equation </u><u>(</u><u>2</u><u>)</u>
x + 4y = 19
x + 4(6) = 19
x + 24 = 19
x = 19 - 24
x = -5
<u>Therefore, the value of y is 6 and value of x is -5</u>
Answer:
The change in available disk space is −6% per episode
Step-by-step explanation:
Given that :
Available disk space changed from 81% to 9% after recording 12 episodes of a show
Each episode requires the same amount of disk space
Change in disk space =
Final % = 9%
Initial percentage = 81%
Change = final value - initial value :
(9 - 81)% = -72%
72% reduction in disk space
Space taken up per episode :
Reduction in space / number of episodes
= -72% / 12
=- 6%
Answer:
4 13/18
Step-by-step explanation:
This problem is equivalent to 17/6 times 5/3, which comes out to 85/18, or 4 13/18.
