Hi so remember the perimeter of a square is 4 times the side. so if the perimeter is 36 then you can divide 36 by 4 to get the answer 9.
36=4^x
36=4x
36/4=x
9=x
to cross check if ever unsure times the (side) by 4 if it matches the given perimeter.
Answer:
9/4:3/8=9/4×8/3=72/12=24/4=6/1=6
Answer:
1/5 2/5
Step-by-step explanation:
There is 5 zones meaning its 1 out of 5.
If you flip twice its double your chance.
Hope This Helps
Answer:
x = 1/2; y = 1/3
Step-by-step explanation:
2x + 3y = 2 Eq. 1
-6x + 12y = 1 Eq. 2
Eq. 1
2x + 3y = 2
2x = -3y + 2
x = -3/2 y + 1
Eq. 2
-6x + 12y = 1
De Eq. 1 sabemos que x = -3/2 y + 1
-6x + 12y = 1
-6(-3/2 y + 1) + 12y = 1
9y - 6 + 12y = 1
21y - 6 = 1
21y = 7
y = 7/21
y = 1/3
Eq. 1
2x + 3y = 2
2x + 3(1/3) = 2
2x + 1 = 2
2x = 1
x = 1/2
Respuesta: x = 1/2; y = 1/3
