As we know Conversion from fahrenheit to celsius is
We can write it also as
F as y and C as x then we can write it as
Answer:
77.44%
49.87%
Step-by-step explanation:
If 12% leaks everyday, on the first day 12% would leak, leaving 100 - 125 = 88% of air
on the second day, 12% of 88% would leak = 0.88 x 0.12 = 0.1056
Air left on the second day = 88% - 10.56% = 77.44%
After a week = (100 - 12%)^7 = 49.87%
180
This is because 12x5x3 = 180
Y + x = 5x + 3
12 - y = x + 2y
Isolate x in the first equation, then substitute its expression into the second equation to find y:
y + x = 5x + 3
x = 5x - y + 3
-4x = -y + 3
x = y - 3/4
---
12 - y = x + 2y
12 - y = (y - 3/4) + 2y
48 - 4y = y - 3 + 8y
48 - 4y = 9y - 3
-4y = 9y -51
-13y = -51
y = 51/13
Substitute this into the first equation to find x:
51/13 + x = 5x + 3
x - 5x = 3 - 51/13
-4x = -12/13
x = 3/13
Lastly, substitute back into both original equations to check work;
y + x = 5x + 3 --> 51/13 + 3/13 = 5(3/13) + 3 --> 54/13 = 54/13
12 - y = x + 2y --> 12 - 51/13 = 3/13 + 2(51/13) --> 105/13 = 105/13
Answer:
x = 3/13
y = 51/13
Hope this helps.
Every term is 3 times the previous onenote that 1/9 times 3/1=3/9=1/3 which is the next term
so 1 times 3=next term=3
next term is 3
