0.75 liter of 0.07 % is used and 0.25 liter of 0.23 % salt is used
<em><u>Solution:</u></em>
We have to 1 liter of final solution
Let "x" be the salt solution of 0.07 %
Then, (1 - x) is the salt solution of 0.23 %
Then final solution should be 1 liter of solution which contains 0.11 % salt
Thus, 0.07 % of "x" is mixed with 0.23 % of (1 - x) to make a solution 0.11 % of 1 liter
<em><u>Thus a equation is framed as:</u></em>
0.07 % of x + 0.23 % of (1 - x) = 0.11 % of 1
Thus 0.75 liter of 0.07 % is used
And,
1 - x = 1 - 0.75 = 0.25
Thus 0.25 liter of 0.23 % salt is used

12(x+4)=60
Answer:
y=6x-4
Step-by-step explanation:
First find the slope using the coordinates of (-1,-10) which will be your first pair x1 and y1. And (3,14) will be x2 and y2. To find the slope use this formula: m= y2-y1/x2-x1
Put the numbers of the coordinates in the formula and you get a fraction of
24/4 = 6 this is the slope
m=6
Then to find the y-int
Pick a coordinate they both will give the same answer. Put it into the point slope formula: y-y1=m(x-x1)
Only use y1, x1, and m which is 6 And solve
y-14=6(x-3) distribute the 6 this gives you
y-14=6x-18 to get y by itself, ADD 14 to both sides of the equal sign
Leaving you with y=6x-4
