Hello,
let's say v the speed of transmission
v=20kB/4s=5 kB/s
Data downloaded =v*t=5kB/s*15s= 75 kB*s/s= 75 kB.
Given:
1,5,25,61.....
To find:
The following number.
Solution:
We can see a pattern in the given sequence.
Using this pattern the next term is the sum of squares of 7 and 8.
Therefore, the next number is 113.
-5x +2/9 +2x- 2/9 =7/9
collect like terms
-3x+0=7/9
cross-multiply
-27x=7
solve for x
x=-7/27
Answer:
44%
Step-by-step explanation:
So you have 2 bottles. One bottle is 8ml and is 80% acid. the other is 12 ml and is 20% acid.
This means there's 6.4 ml of acid in bottle 1(8*0.8) and 2.4 ml of acid in the other one(12*0.2).
The total amount of liquid is 8+12 = 20
The total amount of acid is 6.4+2.4 = 8.8
Percentage of acid in the new solution is 8.8/20 = 0.44 = 44%
Move 6x to the right side
2y = -6x - 14
Divide all numbers by 2 to isolate the variable
2y/2 = -6x/2 - 14/2
y = -3x - 7
