Question

Solve the equation r - 14 = 10







6. Solve the equation m x -8 = 64







7. 3² + 1( 3³ ÷ 3)





8. What is the difference between Expression and Equation? Give example for each.

Answer 1

Answer:

5.)

r - 14 = 10

r = 10 + 14

r = 24

6.)

x - 8 = 64

x = 64 + 8

x = 72

7.)

3² + 1( 3³ ÷ 3)

9 + 1( 9 ÷ 3)

9 + 1(3)

9 + 3 = 12

8.)

Expression:

An expression is a number, a variable, or acombination of numbers.

e.g. 10x + 63 and 5x - 3

Equation:

An equation is made up of two expressions connected by anequal sign.

e.g. ax² + bx + c = 0
