The answer is

Step-by-step explanation:

First we must follow the order of operation: Please, Excuse, My, Dear, Aunt, Sally; Paranthesis, Exponents, Multiplication, Division, Addition, and Subtration.

First it says to look for parenthesis, which there are; so we do that first;.

3(7x) -2 (4 - x)

  ^

21x - 2 (4 - x)

               ^

 21x - 2 times 4 (btw, we took x away because 4 - x)

               ^ (now we do multiplcation)

      21x - 8  

           ^

What is the value of x?<br><br> 3<br> 4<br> 6<br> 8
bekas [8.4K]
The longer sides of the rectangles should be the same value, so we can make the lower part of the equation equal to 18, which is 4.
We can even find the y value by making it equal to 10, which is 3.

Divide the number 480 in a ratio of 3:5
Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).


So divide 480 by 8: 480/8 = 60


Then the ratio is (3x60):(5x60) or 180:300


To check it is correct, add up the two parts to see that they come to 480:


180+300 = 480. All good.


Hope this helps
