Answer: 3x - 9
Step-by-step-explanation: To solve the expression (8x – 2) – (5х – 7) we will be using properties of operations. First, use the commutative and associative properties to move the values next to each other to combine like terms.
(8x – 2) – (5х – 7)
(8x-5x)+(-2-7)
3x-9
So, the subtracted answer is 3x - 9
Answer:
n = 0.38 rotation per second
Step-by-step explanation:
The device rotates according to the mathematical equation :
...(1)
Where n is the rotational speed and is measured in rotations per second (s).
r is radius of the circulator and is measured in meters (m).
We need to find the rotational speed when radius is 1.7 m. Put r = 1.7 m in equation (1).

Hence, the rotational speed is 0.38 rotation per second.
Answer: 31/50
Step-by-step explanation: 0.62= 62/100. After we must find the Greatest Common Factor which is two.
62/2=31 100/2=50
