Answer:
The manufacturing time is 1.5385 minutes per unit.
Step-by-step explanation:
∵ The units manufactured by machine in 1 hour = 39,
We know that,
1 hour = 60 minutes,
∴ The units manufactured by machine in 60 minutes = 39,
That is,
39 units = 60 minutes,
⇒ 1 unit = 
=1.53846153846 ≈ 1.5385 minutes,
Hence, the manufacturing time is 1.5385 minutes per unit.
Answer:
a = -0.8b
Step-by-step explanation:
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-4b' to each side of the equation.
5a + 4b + -4b = 0 + -4b
Combine like terms: 4b + -4b = 0
5a + 0 = 0 + -4b
5a = 0 + -4b
Remove the zero:
5a = -4b
Divide each side by '5'.
a = -0.8b
Simplifying
a = -0.8b
The answer is 36
Answer - 36
Answer:
13x^2 - 7x + 6
Step-by-step explanation:
(9x^2 -7x) - 1(-4x^2 + 6)
(9x^2 -7x) + 4x^2 +6
9x^2 - 7x + 4x^2 + 6
(9x^2 + 4x^2) - 7x + 6
13x^2 - 7x + 6
