Please help me I just want sleep and I want it to be atleast on 75% so I can continue tomorrow cause I’m tried and my back already hurts.

$4

Step-by-step explanation:

Quick tip about 20% tips.

Move the decimal over 1 place to the left and multiply by 2.

For this equation it would look like this:

18.37 ---> 1.837

(1.837)(2) = 3.674

So, if we rounded to the nearest dollar like the question is asking then we round to $4.

Another way to do this is to multiply 18.37 by .20:

(18.37)(.20) = 3.674

Either way it is $4.

I hope this helps!!

problem:

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

f(5/2) = 10/3

i hope this !
