a + 11
Answers
Answer:
We will use the concepts of algebra to identify the operations (addition, subtraction, division, multiplication) in forming the given expressions.
(a) z + 1 = 1 is added to z (Addition)
z – 1 = 1 is subtracted from z (Subtraction)
y + 17 = 17 is added to y (Addition)
y – 17 = 17 is subtracted from y (Subtraction)
(b) 17y = y is multiplied by 17 (Multiplication)
y / 17 = y is divided by 17 (Division)
5z = z is multiplied by 5 (Multiplication)
(c) 2y + 17 = y is multiplied by 2 and 17 is added to the result (Multiplication and addition)
2y – 17 = y is multiplied by 2 and 17 is subtracted from the result (Multiplication and subtraction)
(d) 7m = m is multiplied by 7 (Multiplication)
- 7m + 3 = m is multiplied by -7 and 3 is added to the result (Multiplication and addition)
- 7m – 3 = m is multiplied by -7 and 3 is subtracted from the result (Multiplication and subtraction)
