the sum of a number times 2 and 17 is at most 20

Question

Use the variable c for the unknown number

Answer 1

The expression for the sum can be written as:

2c + 17 ≤ 20

Now, we can solve this inequality:

2c + 17 ≤ 20
Subtract 17 from both sides to isolate the term with c:
2c ≤ 3
Divide both sides of the inequality by 2 to solve for c:
c ≤ 3/2

Therefore, the value of c is at most 3/2.
