||17 ONLY|| I don’t ✨understand✨ this so ya

9/10, 80, and 16

Step-by-step explanation:

If 0.9 is what it was (can't read it lol) then that's like 9/10

And just multiply 16 by 5 is 80 so it's 20% of 80

And the last one is 16$

The second one is B so 80 :)

Step-by-step explanation:

eve and marks ratios are equivalent

step-by-step explanation:

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
