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

4th option is correct xy=-10

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
