Part A: Solve −np − 80 < 60 for n. Show your work. (4 points)
morpeh [17]
Solution:

1) Add 80 to both sides
-np<60+80

2) Simplify 60+80 to 140
-np<140

3) Divide both sides by p
-n<\frac{140}{p}​​

4) Multiply both sides by -1
n>-\frac{140}{p}

Done!

How many lengths of wire, each 3 3/4 inches. long can be cut from a 25-ft roll?
lianna [129]

Answer:

80 pieces of wire.

Step-by-step explanation:

It may not come out evenly. If there is a remainder, it won't matter. Just throw it away and go with the integer answer.

Change 3 3/4 to a decimal

3.75

Change the 25 foot roll to inches.

25 feet * 12 inches / foot  = 300 inches.

Now how many pieces of wire do we get.

1 piece of wire/3.75 inches = x pieces of wire / 300 inches

3.75 * x = 300

3.75 * x / 3.75 = 300 / 3.75

x = 80
