Question

Solve for d when t = 0, t = 3, t = 5 d =2t

Answer 1

when t=0 d=2*0=0
when t=3 d=2*3=6
when t=5 d=2*5=10

Answer 2

• When t = 0, d = 0
• When t = 3, d = 6
• When t = 5, d = 10

Concept:

Here, we need to understand the idea of evaluation.

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

PART ONE: Find d when t = 0

Given expression

d = 2t

Substitute value into the expression

d = 2 (0)

d = 0

PART TWO: Find d when t = 3

Given expression

d = 2t

Substitute value into the expression

d = 2 (3)

d = 6

PART THREE: Find d when t = 5

Given expression

d = 2t

Substitute value into the expression

d = 2 (5)

d = 10

Hope this helps!! :)
