8 0

Answer:

x= - 1   ; z = - 9

Step-by-step explanation:

The requester asked for 8 and 11, but I can't see the problem in the picture.

Here are 7 and 10:

#7 5x - 4x + 2 = 1

Combine 5x and -4x to get x

x + 2 = 1

Subtract 2 from both sides

x = -1

#10 -40/2 = z - 11

Simplify -40/2 to get -20

-20 = z - 11

Add 11 to both sides

z = -9

If you want 8 and 11, reupload the problem with a picture that includes them.

Mrs. Owens was making Thanksgiving dinner for 10
saul85 [17]

Well if she is making dinner for 10 people and each person want 2 pieces then you need to multiple 10 x 2 = 20. So she is going to need to make 20 pieces.

If each of her pumpkin pies only has 8 pieces then she is going to have to make 3 pies.

3 pies x 8 pieces = 24 pieces of pumpkin pie. So she has to make 3 pies because she needs 20 pieces since everyone wants 2.

In conclusion Mrs. Owens has to make 3 pies and she is going to have 4 pieces left over.

aniked [119]

Answer:

1) triangular garden is larger

2) 1.46 square feet

3) 56.5 square inches

4) 557.1 sq in

5) 216 sq in

Step-by-step explanation:

1) Area of circlular garden: 78.54

Area of triangle garden: 80

2) 80 - 78.54 = 1.46

3) 12/2 = 6

6^{2}\pi = 113.1

113.1/2 = 56.5

4) area of square: 20(20) = 400

area do semicircle: (20/2)^{2} \pi/2 = 157.1

400 + 157.1 = 557.1

5) square: 144

triangle: 144/2 = 72

144 + 72 = 216
