Answer

Step 1: Son's age = x years Step 2: Lady's age is 28 years more than x Step 3: Add 28 to x Answer: (x + 28) years…

Card 2Generating algebraic expressions

If n is 12 times x, write the algebraic expression for n.

Answer

Step 1: 12 times x means 12 × x Step 2: Write the product as a single term Answer: n = 12x…

Card 3Generating algebraic expressions

A two-digit number has unit digit x and ten's digit y. Write the number.

Answer

Step 1: Ten's digit is in the tens place, so it contributes 10y Step 2: Unit digit contributes x Step 3: Add them Answer: 10y + x…

Card 4Generating algebraic expressions

Write the expression for 5 times a decreased by 6 times b and then decreased by (8 + c).

Answer

Step 1: 5 times a = 5a Step 2: Decreased by 6 times b means subtract 6b Step 3: Then decrease by (8 + c) Answer: 5a - 6b - (8 + c)…

Card 5Constants and variables

Classify each as constant or variable: 3 + 8, x + y - z, 6 + x.

Answer

Step 1: 3 + 8 uses only constants, so it is a constant Step 2: x + y - z uses only variables, so it is a variable Step 3: 6 + x uses constants and variables, so it is a variable Answer: constant, vari…

Card 6Terms and expressions

Is 3x × 4y one term or two terms?

Answer

Step 1: Product signs do not separate terms Step 2: 3x × 4y is a product of factors Step 3: So it is one term Answer: One term…
