Answer:
5x+120
Step-by-step explanation:
first you add the 2x x and x and x that would get you 5x and then add the 20 and 10 and 80 that would get you 120
Answer: 9/10 of the book.
Step-by-step explanation:
1. Convert all of the fractions to have a common denominator. 6, 5, and 3 are all multiples of 30, so we can convert the fractions to 30ths.
1/6 = 5/30
2/5 = 12/30
1/3 = 10/30
2. Add the fractions together to find the whole amount of the book Joyce has read.
5/30 + 12/30 + 10/30 = 27/30
3. Simplify
27/30 -> 9/10
The force created by the object is 3.75 Newton.
Given
Mass of the object (m) = 1250 grams
Convert 1250 grams to kilograms by dividing it by 1000.
Mass (m) = 1.25 kg
Acceleration of the body (a) = 3 
From Newton's second law we know 
By Substituting in the above equation we get
Force = 1.25 x 3
Force = 3.75 
It can also be written as force = 3.75 N
Hence Force created by the body is 3.75 Newton.
