Step-by-step explanation:
4) split this into two shapes, a rectangle and a triangle...
Rectangle: base(height)
14(7)=98
Triangle: 1/2base(height)
Find the height: 14-7=7
1/2(14)(7)=49
Add them together: 98+49=147
147in^2
5) split this into two shapes, a square and a triangle...
Square: base(height)
20(20)=400
Triangle: 1/2base(height)
1/2(20)(10)=100
Add them together: 400+100=500
500m^2
6) split this into 2 shapes, a rectangle and a triangle...
Rectangle: base(height)
6(5)=30
Triangle: 1/2base(height)
1/2(6)(3)=9
Add them together: 30+9=39
39yd^2
7) I can't see the number behind the m. Please tell me what it is and then I'll help you!
8) split this into 2 shapes, a rectangle and a triangle...
Rectangle: base(height)
5(2)=10
Triangle: 1/2base(height)
1/2(5)(3)=7.5
Add them together: 10+7.5=17.5
17.5ft^2
9) split this into 2 shapes, a rectangle and a triangle...
Rectangle: base(height)
13.5(18)=243
Triangle: 1/2base(height)
1/2(13.5)(9)=60.75
Add them together: 243+60.75=303.75
303.75cm^2
I hope this helps:)

Answer:
The answer would be, 2.75
Step-by-step explanation:
Add all the numbers up:
0+1+1+2+3+4+5+6=22
Divide the answer by the amount of numbers:
22÷8=2.75
Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
