What is the missing numerator? Four fifths minus blank over nine equals six forty fifths
A) 7
B) 6
C) 5
D) 4

6

Step-by-step explanation:

(4/5)-(x/9)=6/45

6/45=(6/3)/(45/3)=2/15

4/5-(x/9)=2/15

(4/5)-(2/15)=(x/9)

(4*3)/(5*3) = 12/15

12/15-2/15=10/15

10/15=2/3

2/3=6/9

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

at least two
