Answer:
It's A I hope that helps
Step-by-step explanation:
First, we define variables:
x: small hat
y: medium hat
z: large hat
We now write the system of equations:
x + y + z = 47
5.50x + 6y + 7z = 302
-3x + y = 0
We can write the system in matrix form as:
Ax = b
Where,
A = [1 1 1; 5.50 6 7; -3 1 0]
b = [47; 302; 0]
x = [x; y ; z]
Solving the system we have:
x = 6
y = 18
z = 23

Answer:
Step-by-step explanation:
we are being told that each square is one unit. so, look at peak to peak and count the units.
1,2,3,4,5,6,7
From peak to peak is 7 units, so the period is 7
