Let x = Class A
Let y = Class B
Let z = Class C
Equations from problem:
x - 160 = y
2/3x = z
y + 92 = z
Solving through substitution:
2/3x = y + 92
2/3x = (x - 160) + 92
2/3x = x - 68
-1/3x = -68
3(-1/3x) = 3(-68)
-x = -204
x = 204
Now substitute x in the first equation to get y:
204 - 160 = y
44 = y
44 = Class B
There are 44 folded paper cranes in Class B.
Answer:
C
Step-by-step explanation:
Hey there!
So, x is being multiplied by itself three times. Therefore, the exponent needs to be three.
Hope that helps! :)
Answer:
Yes, cells are living, because they make up living things, and can do what most living things are able to, like reproduce.
(3 x 3 - 6) = ?
First, multiply 3 x 3, which = 9
(9 - 6)
Then subtract 9 by 6, giving you 3.
So, :
(3 x 3 - 6) = 3
Part 1:
perimeter of a rectangle = 2(L + W)
W = 5/6 L
perimeter of a rectangle = 2( L + 5/6L)
Part 2:
perimeter of the rectangle is 44 inches
perimeter of a rectangle = 2(L+5/6L)
44 = 2(L+5/6L)
44 = 2L + 10/6 L
44 = 3 2/3 L
L = 12
W = 5/6 L
W = 5/6 x 12
W = 10
Area = L x W
Area = 12 x 10
Area = 120 square inches
