Two less than the product of a number and three evaluate when f = 4.5. evaluating an algebraic expression write and evaluate the expression shown on the left. then, check all that apply. write the expression as 2 – 3f. write the expression as 3f – 2. write the expression as 2f – 3. the value when f = 4.5 is 6.75. the value when f = 4.5 is 6. the value when f = 4.5 is 11.5.

Write the expression as 3f – 2.

The value when f = 4.5 is 11.5.

Step-by-step explanation:

Let f be the number.

Then the product of the number and three is 3f.

Two less than 3f is 3f -2.

f(4.5) = 3×4.5 - 2

f(4.5) = 13.5 - 2

f(4.5) = 11.5

x=30

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
