Answer:
is the better unit price.
Step-by-step explanation:
120 is the better unit price because if you divide 120 divided by 6 you get 20 and if you divide 200 divided by 8 you get 25 so then you would pick the cheapest one because of its price and amount.

<h3>What is numerical computing?</h3>
Numerical computing is a technique for tackling difficult mathematical problems with only basic arithmetic operations.
The method entails the creation of mathematical models that can be solved using arithmetic procedures.
The three characteristics of numerical computing are accuracy, efficiency, and stability.

Answer:
x = -4, y = 7, z = 2.
Step-by-step explanation:
4x + 2y + 5z = 8......(1)
5x + 3y + 4z = 9......(2)
6x + 3y + 3z = 3......(3)
Subtract: equation (2) - equation (3):
-x + z = 6 ........(4)
Multiply (1) by 3 and (2) by 2:
12x + 6y + 15z = 24 .........(5)
10x + 6y + 8z = 18 ...........(6)
Subtract: (5) - (6):
2x + 7z = 6..............(7)
Multiply equation (4) by 2:
- 2x + 2z = 12.........(8)
Add (7) + (8):
9z = 18 , so z = 2.
Substitute for z in equation (4)
-x + 2 = 6
-x = 4 so x = -4.
Now find y by substituting in equation (1):
4(-4) + 2y + 5(2) = 8
2y = 8 + 16 - 10 = 14
y = 7.
x=83°
Step-by-step explanation:
In the given figure,
Sum of all angles of triangle = 180°
So, 44° + 53° + x = 180°
97° + x = 180°
x = 180 - 97
x = 83°
