6.5/x=10/40;x=26

Step-by-step explanatio

Step-by-step explanation:

Remark

There are a couple of ways that would produce the right answer. The proportion must be set up so that likes are on the numerator and denominator.

6.5 vertical height of the small triangle/ horizontal small 10  =

x vertical of the tree/ 40 horizontal of the tree.

Notice what we have

vertical / horizontal = vertical / horizontal

6.5 / 10 = x / 40         Cross multiply

6.5 * 40 = 10 * x

260 = 10 * x               Divide by 10

26 = x

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
