First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).
For 3, I would count 3 numbers to the right from zero.
For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.
For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.
For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.
Answer:
12 cans
Step-by-step explanation:
->link is 54 feet and it's width is 30 feet
Therefore,
Area = 54 x 30 = 1620ft²
Supposing each can of wood stain covers 135 ft.²
In order to find that how many cans will he need to cover the port, we'll divide the area of core by the area of each can of wood stain.
so, 
= 12 cans
Therefore, he'll need 12 cans to cover the port.
Answer:
5m+ t = r
Step-by-step explanation:
m is the miles. t is how long she took. and r is for the time limit of the race.
Two times a number less one hundred and twenty-five is equal to four hundred
Subtract 2 from 12. 12-2 is 10. You can subtract 10 with 4, and then add 2. (10-4)+2=8.
