Answer:

<u>Question #1</u>

  • x and its opposing side are equal in length.
  • One of the sides have no fence.

<u>Set up an equation to find x:</u>

x+x+10=26\\2x=26-10\\2x=16\\x=8

<em>The length of the side marked x is 8.0 m.</em>

<u>Question #2</u>

  • New length = 10 + 1 = 11 cm
  • New width = x
  • New perimeter = old perimeter = 34 cm

Set up an equation to find x

11+11+x+x=34\\2x=34-22\\2x=12\\x=6

<em>The new width is 6 cm.</em>

Hhellp pwease I want to know what's wrong and right
Studentka2010 [4]

Answer:

A: False

B: False

C: True

D: True

E: False

F: True

G: True

H: True

Step-by-step explanation:

A: 9(x - 2) = 9x + 2

9x - 18 = 9x + 2 FALSE

B: 65 - y = y - 65

(equation rearranged) -y + 65 = y - 65 FALSE

C: g (times) h = h (times) g     (TRUE due to the commutative property of multiplication)

D: a (times) 0 = 0      (TRUE because anything times 0 equals 0)

E: (4 (times) 2) - r = 4 (2 (times) r)

8 - r =  8 - 4r FALSE

F: k + 0 = k TRUE

G: (a + x) + y = a + (x + y)

a + x + y = a + x + y TRUE

H: 5(2x - 9) = 10x - 45

10x - 45 = 10x - 45 TRUE

NEED HELP WITH THIS PLEASE
marin [14]

Answer:

-25 + 75 = 50

Step-by-step explanation:

Since we don't know the value of the bar, we will call it x.

-25 + x = 50

Add 25 to both sides to find the value of x.

x = 75

You can also double check this answer by doing simple math.

-25 + 75 = 50
