Which of the following equations could be used to determine the value of X

D

Step-by-step explanation:

If the original price is x and you deduct 3, you'l have x - 3.

If you buy 4 of them, you multiply that price by 4, giving you 4(x - 3).

Then, if that value is equal to 27, you get 4(x - 3) = 27

D

Step-by-step explanation:

We can make each part of the problem into a expression, and combine them.

Part 1: A picture frame that normally costs $x is discounted by 3.

x-3

Part 2: I decided to purchase 4 of the discounted picture frames

4(x-3)

You are buying 4, and each costs x-3.

Part 3: The total cost of the four frames, excluding tax, is $27.

4(x-3)=27

rotation point l

step-by-step explanation:

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
