Someone ordered 430 shirts . they ordered twice as many red as white and 50 more blue than white . how many of each color did he order ?

If white, is w, then you have the equation w+2w+w+50=530.

4w=480, so there are 120 white colored shirts.

There are 240 red colored shirts.

There are 170 blue colored shirts.

White 95 , red 190 and blue 145.

Step-by-step explanation:

Let number of white shirts ordered be w

Then the  number of red = 2w and number of blue = w + 50 . Thus:-

w + 2w + w + 50 = 430

4w + 50 = 430

4w =  430 - 50 = 380

w =  380 / 4 = 95

So red = 190 and blue =  145

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
