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:
the coach did purchase 23 large hats
d. 23
Answer:
X + Y = 1 ------1
X - 2y = 4 ------2
Solving by substitution method
X = 4 + 2y -----3
Putting the value of X in equation 1
4 + 2y + y = 1
4 + 3y = 1
3y = 1 - 4
3y = (-3)
y = (-3) /3
<h3>y = (-1) </h3>
Putting value of y in equation 3
X = 4 + 2(-1)
X = 4 - 2
<h3>X = 2 </h3>
3 (15-6)+(18-12)^2=
3 (9) + (6)^2=
27 + 36 =
63
Answer:
1. Priests and rulers of society.
2. Warriors
3. Merchants
4. Blacksmiths
Step-by-step explanation:
1. They were born into status and religion was a big part of society so priests would be treated well.
2. Warriors were able to work their way up in society and became respectable.
3. These were lower level people right under warriors and didnt lead a bad life.
4. Rejects and weren't able to have rights
Step-by-step explanation:
a < (a + b)/2 < b
Solve the first inequality.
a < (a + b)/2
2a < a + b
a < b
Solve the second inequality.
(a + b)/2 < b
a + b < 2b
a < b
Both inequalities are true. Therefore, a < (a + b)/2 < b.
