Answer:
B
Step-by-step explanation:
One way to tell is to put both equations into slope-intercept form. That form is usually written where <em>m</em> is the slope and <em>b</em> is the y-intercept.
Solve the first equation for y.
The slope of this line is -3, and its y-intercept is 5/2.
Solve the second equation for y.
The slope of this line is -3 and its y-intercept is 2.
The lines are parallel because they have the same slope and <u>different</u> y-intercepts. There is no solution to the system.
To answer this problem, you should just substitute some figures in order to get the required amount.
So, let a be the amount of 10% iodide solution
So...
4 (3) + 10a = 6 (3+a)
[4 represents the silver iodine solution, the 3 is the liters, while we are looking for the 6% solution]
12 + 10a = 18 + 6a
10a - 6a = 18 - 12
4a = 6
a = 6/4
a = 3/2
So you will need 3/2 or 1.5 liters of 10% iodide solution.
Answer:
if you mean the face of the triangle the area equal 40 by 5×8=
and the little triangle on the left his area is 6
if you want the full area of prymaid its 24+6+6+40+32=108 its all figure areas sorry i cant understand engilish very well so i write all that
