That'd be true only if the value of "s" is the exact same one for both
namely if sec(s) = cos(s)
then solving for "s"
thus
First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway thus

solve for "x"
Answer:

Step-by-step explanation:
Start by converting 5 meters to centimeters. Note 1 meter = 100 centimeters.
We can set up a unit converter:

The meters cancel out leaving us with:

The scale factor is:

1) (solve for Y 1st)
-4y=16
y=-4
slope=0 y-inter= -4
2)(solve for X 1st)
6x=12
x=2
slope=undefined y-inter= none
The answer the this problem can be either 6/15 or 2/5
