What is an expression which combines numbers and operations?

Answers

An expression that combines numbers and operations is a mathematical statement that represents a calculation or computation.

An expression can involve various arithmetic operations such as addition, subtraction, multiplication, division, exponentiation, and more.

Here are some examples of expressions:

Addition: 5 + 3

Subtraction: 10 - 2

Multiplication: 4 × 6

Division: 20 / 5

Exponentiation: 2³ (2 raised to the power of 3)

Combination: (5 + 3) × 2

In the last example, the expression combines addition and multiplication. Parentheses can be used to indicate the order of operations, ensuring that calculations are performed correctly according to mathematical conventions (e.g., multiplication before addition).

There are 30 homes in Neighborhood A. Each year, the number of homes increases by 20%. Just down the road, Neighborhood B has 45 homes. Each year, 3 new homes are built in Neighborhood B.Part A: Write functions to represent the number of homes in Neighborhood A and Neighborhood B throughout the years. (4 points)
Part B: How many homes does Neighborhood A have after 5 years? How many does Neighborhood B have after the same number of years? (2 points)
Part C: After approximately how many years is the number of homes in Neighborhood A and Neighborhood B the same? Justify your answer mathematically. (4 points)

Answers

Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.

N.A = 30 (1.20)^t
N.B = 45 + 3(t)

t = 5

N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
N.B = 45 + 3(5) = 45 + 15 = 60
