Answer:
Luis’s, because he flipped the inequality sign when he subtracted
Step-by-step explanation:
7.2b + 6.5 > 4.8b – 8.1.
Amelia started by subtracting 7.2b from both sides to get
6.5 > –2.4b – 8.1
Correct
Luis started by subtracting 4.8b from both sides to get
2.4b + 6.5 < – 8.1
Incorrect
Shauna started by subtracting 6.5 from both sides to get
7.2b > 4.8b – 14.6
Correct
Clarence started by adding 8.1 to both sides to get
7.2b + 14.6 > 4.8b
Correct
Luis’s is incorrect because he flipped the inequality sign when he subtracted

Answer:
48,400 yd²
Step-by-step explanation:
(220+180)/2*260=52000
1/2(180)(60)=5400
So the total area is 52000+5400=57400
Basketball court=2400
Picnic area = 4200
Playground = 40x50 + 10x40=2400
2400+4200+2400=9000
57400-9000=48400
Answer:
m= -1/2, (0,5), (10,0)
Step-by-step explanation:
Let us write it in slope intercept form, y=mx +b where m is the slope:
2x+4y=20
4y= -2x+20
y= -1/2x+5
Therefore, the slope is -1/2
The y intercept can be found when we substitue 0 as x.
y= -1/2*0 +5
y=0+5
y=5
(0,5)
The x intercept can be found when we substitute 0 as y.
0=-1/2x+5
-5 =-1/2x
x= 10
(10, 0)

Having the length of a side(noticed with l), the volume of the cube is equal to:
V = l*l*l
V=l^3
To find the numeric value of l: l =
![\sqrt[3]{V}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7BV%7D%20)
In our problem V = <span>256
l = </span>
![\sqrt[3]{256} = \sqrt[3]{2^8} = 2^2\sqrt[3]{2^2} = 4 \sqrt[3]{4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B256%7D%20%3D%20%20%5Csqrt%5B3%5D%7B2%5E8%7D%20%3D%20%202%5E2%5Csqrt%5B3%5D%7B2%5E2%7D%20%20%3D%204%20%5Csqrt%5B3%5D%7B4%7D)
