12. If a four-yard string is cut into three equal pieces. how long will each piece be?
1.
4ft 2. 31/2ft
3. 31/3ft
4. 3ft
5. 21/4ft

the answer is A. 4ft

Step-by-step explanation:

12 feet in the 4 yards 12 divided by 3 equal 4

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

answer: (3,11) is your answer.
