I need someone to write me an equation with a distributive property?

1 answer:

6 0

The distributive states that a(b + c) = ab + ac.

The distributive property is useful of simplifying parentheses.

Example:

3(x - 1) + 5 = 20

3(x - 1) expression can be simplified with the distributive property.

3(x - 1) + 5 = 20
3x - 3 + 5 = 20

After this you would combine any like terms and solve for x.

There can be also more than two terms in the parentheses:

a(b + c + d) = ab + ac + ad.

Answer:

Part 1: 114,570,685 people

Part 2: The population grew by 2.5% (1,722,862 people)

Step-by-step explanation: For part 1 you would multiply 100,236,820 by 1.143 because of the fact that your percentage is increasing. so the 1 before the decimal point stands for 100% of the starting number and the .143 stands for the 14.3% that the population is increasing by.

Part 2 you would divide 53,594,378 by 55,317,240 to get approximately .975. .975 shows that 53,594,378 is about 97.5% of 55,317,240. You then subtract the numbers 100 and 97.5 to get 2.5. 2.5 is the percentage that the population is increasing by. So, then you could just subtract 55,317,240 and 53,594,378 to get 1,722,862. This is the amount of people the population increased by. Then you just put your answer that the population increased. That it increased by 2.5% and 2.5%= 1,722,862 people

I hope this helps you :)
