PL HELLL RIGHT NO I NEED THIS ASAPP 3. If I buy ice cream it is 4$ per scoop. Write an equation of this?

4x

Step-by-step explanation:

Let x be the amount of scoops you get, a variable (unknown). Every scoop is 4 dollars. To know how much x scoops would cost, you would multiply x by four (ex. 5 scoops= 4(5)).

I hope this helps!

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
