Amelia, Luis, Shauna, and Clarence used different approaches to solve the inequality
mezya [45]

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

Help me please if it right I give brainliest I promise
Ksenya-84 [330]

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

Let the number of games, x, and the number of rides y, For 2x + 4y = 20, what is the slope of the graph? What is the slope? (Hin
hram777 [196]

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)

A farmer is building a grain silo storage. He estimates that will need 256 cubic yards of storage. The grain silo will be shaped
tigry1 [53]
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}

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}
