-1/3=-3-/9
-4/9-3/9=-7/9
z-7/9=5/9
7/9+5/9=12/9
z=1 1/3
Answer:
<h2><u><em>
A) -1</em></u></h2><h2><u><em>
B) -1.5 or -3/2</em></u></h2>
Step-by-step explanation:
Solve 3-4 and (1⁄2)-2
3 - 4, 4 is greater than 3, so the result is negative (-1)
3 - 4 = -1
-----------------
1/2 is equal to 0.5, also here 2 is larger and we will have a negative result (-1.5 or -3/2)
1/2 - 2 =
0.5 - 2 = -1.5 or -3/2
Answer:
The student took 2.5 minutes to paint 1 square foot.
Step-by-step explanation:
In order to know how long the student took to paint each square foot we first need to know the total area of the bulletin board. Since it is a rectangle we can compute it's area by multiplying the width and the height. That is:
area = 2*3 = 6 square foot
Since the student took 15 minutes to paint the whole board the pace at which he was working can be calculated by dividing the total area of the board by the time he took to paint all of it. So we have:
pace = 6/15 = 0.4 foot/min
To find how long it took him to paint 1 square foot we can divide it by the pace he was painting. We have:
time = 1/0.4 = 2.5 minutes
The student took 2.5 minutes to paint 1 square foot.

Answer:
189 gallons
Step-by-step explanation:
7 gallons for 3 classrooms, so 7/3 for 1 classroom
multiply 7/3 * 129 to get 301 gallons at North High School
multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary
301 - 112 = 189 gallons more at North High School than at Edgewater Elementary
