Apiece of wood is 10 1/2 feet long. you cut off 3 3/8 feet to repair your living room floor. how much wood is left? write your answer as a decimal form to the thousandths place.

7.125 feet

Step-by-step explanation:

1. convert both fractions to decimals by dividing numerator by denominator

    10 1/2 = 10.5

    3 3/8 = 3.375

2. Subtract 10.5-3.375 = 7.125 feet left

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

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
