Because they are like terms that is the lowest they can go
change to improper fractions
77 1/2 = 145/2
2 1/4 = 9/4
divide
145/2 divide 9/4
copy dot flip
145/2 * 4/9
580/18
290/9
32 2/9
it will fit into 32 bags with 2/9 left over
We have 32 full bags * 2.25 = $72.00
Answer:

Step-by-step explanation:
Take out 3x from both sides:
5x - 3x = 3x - 3x
2x = 0
2x + 9 = 1
Take out 9 from both sides:
9 - 9 = 1 - 9
0 = -8
Divide 2 from both sides:


The area of the model is 80 square foot
Step-by-step explanation:
Let the area of the house model be 'a'
The scale = 1:50
The area of the house= 4000 square foot
Area of the model =4000/50
a = 80 square foot
The area of the model is 80 square foot
The correct answer is B.
Explanation
Since each interval mark is 1/4 of a unit, we will write this as 0.25. For the first point, 4 interval marks to the left of the y-axis makes it a negative number; 4(0.25) = 1; this makes the x-coordinate of this point -1. 2 interval marks above the x-axis makes it positive; 2(0.25) = 0.5; this makes the y-coordinate 0.5. This makes the first ordered pair (-1, 0.5).
The second point is on the y-axis. This makes the x-coordinate 0. It is 5 intervals above the x-axis; this makes it positive. 5(0.25) = 1.25 will be the y-coordinate, making the point (0, 1.25).
The third point is 3 intervals to the right of the y-axis; this makes it positive, and 3(0.25)=0.75 for the x-coordinate. It is 3 intervals below the x-axis; this makes it negative, and 3(0.25) = 0.75, making the y-coordinate -0.75. This puts the third point at (0.75, -0.75).
