Question

Evaluate the algebraic expression 1.5t-7.2 for each given value.

Value of T
6
-5

What are the expressions for both numbers

Answer 1

1.8 and -14.7

Explanation:

its just to substitute it as t and simplify

Answer 2

1.8 and -14.7

Explanation:

Given the algebraic expression 1.5t-7.2, to get the value of the expression when t = 6, we will substitute the value of t in the given equation to have;

1.5(6)-7

= 9.0-7.2

= 1.8

Similarly when t = -5, the expression 1.5t-7.2 gives;

1.5(-5)-7.2

= -7.5-7.2

= -14.7

Therefore the expression of the equation at x = 6 is 1.5(6)-7.2 gives 1.8 will at x=-5 gives 1.5(-5)-7.2 which gives -14.7
