Hey there!
-11b + 7 = 40
- SUBTRACT by 7 on each of your sides.
-11b + 7 - 7 = 40 - 7
Cancel out: 7 - 7 because that gives you 0
Keep: 40 - 7 because it helps us solve for our answer
40 - 7 = 33
11b/-11 = 33/-11
Cancel out: -11b/-11 because it equals 1
Keep: 33/-11 because it gives you -3
33/-11 = 33 ÷ -11 = 3
<h3>
<u>b</u><u> = -3 </u></h3>
Good luck on your assignment and enjoy your day!

Answer:
the perimeter to the nearest hundred is 256
Answer:
Area = l × w , where l is length and w is width of the room.
Step-by-step explanation:
Length of the room is given to be l units
Width of the room is given to be w units.
The shape of the room is given to be rectangle.
Also, it is given that the area of the rectangle can be calculated by multiplying its length and the width.
So, in order to calculate the area of the rectangle shaped room we multiply the given length of the room l and the given width of the room w.
Hence, The area of the room is given by :
Area = l × w , where l is length and w is width of the room.

Answer:
x = 2
Step-by-step explanation:
First isolate the variable:
10x - 4 = 16
+4 +4
10x = 20
Then get x by itself:
10x = 20
x = 20/10
x = 10
