Question

In 17 - 20 tell how many terms each expression has. 17. -5 - g, 18. 3 1/2b, 19. v/3 2 • 5, 20. 16.2 - (3 • 4) (14 / 2)

Answer 1

The given expressions contain different numbers of terms, with the first and last containing two terms each, and the middle two containing one term each, assuming there are no additional operations between numbers in these expressions.

Step-by-step explanation:

The question asks us to determine how many terms are in each of the given expressions. Let's analyze them one by one:

1. -5 - g has two terms: -5 and -g.
2. 3 1/2b is a single term, as the fraction 3 1/2 is a coefficient multiplying variable b, so there is one term.
3. v/3 2 • 5, which appears to be written incorrectly, could mean v/(3 × 2) × 5 which is v/6 × 5. Assuming it's one complete term with a mix of operations, there is one term. If the expression is separated by spaces to indicate addition or subtraction, which is not clear from the question, then the number of terms could change.
4. 16.2 - (3 × 4) (14 / 2), here we perform the operations inside the parentheses first which are subtractions and multiplications. The expression simplifies to 16.2 - 12 × 7, and after we do the multiplication, we have 16.2 - 84, which is a single subtraction expression with two terms: 16.2 and -84.
