Answer:

x = 1/3

Step-by-step explanation:

Hello,

we can draw the two lines defined by

   y = 4 - x

   y = 2x + 3

And search for the intersection point as below

This is the point A (1/3, 11/3)

Do not hesitate if you have any question

Thanks

Answer:

Step-by-step explanation:

Graph the two lines separately but on the same graph paper, and then from the completed graph read off the coordinates of the point of intersection.

y = 4 - x has a y-intercept of 4 and a slope of -1.  Plot the point (0, 4) and then draw a line with slope -1 through it.

y = 2x + 3 has a y-intercept of 3 and a slope of 2.  Plot (0, 3) and then draw a line with slope +2 through it.  

As a check, solve for x and y algebraically:

4 - x = 2x + 3 becomes 1 - x = 2x, or 3x = 1.  Then x = 1/3.

Use y = 4 - x to find the y value when x = 1/3:

y = 4 - 1/3 = 11/3

Thus, the solution is (1/3, 11/3)

question 20

40 gallons, 12 concentrate, 28 water

this is a fraction of 12/28

simplification: (12) divided by 12 / (28) divided by 12

1/2

1 part concentrate 2 parts water per each of the 40 total gallons.

so color in 33% for concentrate and 66% water

I am totally not wrong  :D:D:D:D
