Algebraic Expressions
1. Solve Exercise 7.1 Page 24 Mathematics Textbook Grade 7
Problem Statement: Write the algebraic expression representing:
a) Half the sum of x and y.
b) The sum of x and y multiplied by the product of x and y.
Solution Guide:
Write operations with x and y.
Answer:
2. Solve Exercise 7.2 Page 24 Mathematics Textbook Grade 7
Problem Statement: Write the algebraic expression representing the area of a trapezoid with two bases a and b, and height h (a, b, and h have the same unit of measurement).
Solution Guide:
The area of a trapezoid is the sum of the lengths of its two bases multiplied by its height (all in the same unit) and then divided by 2.
Answer:
The algebraic expression representing the area of a trapezoid with two bases a and b, and height h is:
3. Solve Exercise 7.3 Page 24 Mathematics Textbook Grade 7
Problem Statement: Calculate the value of the expression:
Answer:
4. Solve Exercise 7.4 Page 24 Mathematics Textbook Grade 7
Problem Statement: A farmer uses two pumps to irrigate the garden. The first pump can pump 5 m3 of water per hour. The second pump can pump 3.5 m3 of water per hour.
a) Write the algebraic expression representing the amount of water pumped by both pumps, if the first pump runs for x hours and the second pump runs for y hours.
b) Using the result from part a, calculate the total amount of water pumped by both pumps when x = 2 (hours), y = 3 (hours).
Solution Guide:
a) The amount of water pumped by both pumps = the amount of water pumped by the first pump in x hours plus the amount of water pumped by the second pump in y hours.
b) Substitute x = 2, y = 3 into the expression and then calculate the value of that expression.
