Question

Evaluate the expression 50-t when t equals -10,20 or 25 then complete the table to show the values.

Answer 1

Then the table will be,

• (-10, 60)
• (20, 30)
• (25, 25)

Explanation:

1) 50 - t, when t = -10 is?

→ 50 - t

→ 50 + 10

→ 60

Thus, the answer is 60.

2) 50 - t, when t = 20 is?

→ 50 - t

→ 50 - 20

→ 30

Thus, the answer is 30.

3) 50 - t, when t = 25 is?

→ 50 - t

→ 50 - 25

→ 25

Thus, the answer is 25.

Answer 2

Given

• Expression 50 - t

Evaluate its value with given t-values

• t = - 10 ⇒ 50 - (-10) = 50 + 10 = 60
• t = 20 ⇒ 50 - 20 = 30
• t = 25 ⇒ 50 - 25 = 25

The table should have ordered pairs

• (- 10, 60), (20, 30), (25, 25)
