Answer:
40
Step-by-step explanation:
Answer:
d. 23
Step-by-step explanation:
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
hope this helps
correct me if this is wrong
1/8+1/3. The denominator is changed to 24. 1/8 will turn to 3/24 and 1/3 will turn to 8/24. 3/24+8/24= 11/24.
