Answer:

The ratio of x:y is 1/2

Step-by-step explanation:

Let

x----> the number of Kg of brand A

y ---> the number of Kg of brand B

we know that

400x+280y=320(x+y)

400x+280y=320x+320y

400x-320x=320y-280y

80x=40y

x/y=40/80

x/y=1/2

How to simplify please help
Luda [366]

Okay, the image is a little tough to see, but I believe it looks something like this:

(5² -10 / 17 - 3 * 4) -1

The first step [remember PEMDAS] is parentheses

Next comes Exponents:

(25 - 10 / 17 - 3 * 4) -1

Then Multiplication:

(25 - 10 / 17 - 12) - 1

Then Division [which we can't do yet since it isn't fully simplified], so we skip to Addition... nothing again, then subtraction.

(15 / 5) - 1

Then we can divide:

(3) - 1

Then subtract!

2

The answer to your problem is 2.

Hope that helps!
