Let’s use y as a replacement for a number. You would do 3y-7 since you multiply by three and take away seven.

Answer:

  D. x to the power of nine

Step-by-step explanation:

The applicable rule of exponents is ...

  (x^a)^b = x^(ab)

You have a=3/2, b=6, so ab = 3/2·6 = 9.

  (x^(3/2))^6 = x^(3/2·6) = x^9

a group friends ordered 3 burgers and 3 medium fries for a total of 20.25 .Another group of friends ordered 5 burgers and 8 medi
matrenka [14]
Answer: a burger is $5.25, fries are $1.50

b = burger, f = fries
3b + 3f = 20.25
5b + 8f = 38.25

First, solve for b in terms of f
3b = 20.25 - 3f
b = 6.75 -f

Then substitute that for b in the other equation to solve and get a numerical value for f.

5(6.75 -f) + 8f = 38.25
33.75 -5f +8f = 38.25
33.75 + 3f = 38.25
3f = 4.5
f = 1.5

Now substitute that in to get a numerical value for b
b = 6.75 - 1.5
b = 5.25

Checking the math:
3b + 3f = 20.25
3(5.25) + 3(1.5) = 15.75 + 4.5 = 20.25
