Answer:

It's just a simultaneous equation

Step-by-step explanation:

Let a big bag of sugar = x

Let a small bag of flour = y

x+x+y = 12kg

2x+y = 12kg ... 1

x-y = 2kg ... 2

Add 1 and 2

2x+y = 12

+

<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>

3x = 14

x = 14/3 = <u>4.66</u>

Substitute value of x into 1

2(4.66)+y = 12

9.333 + y = 12

12 - 9.333= 12

y = <u>2</u><u>.</u><u>6</u><u>6</u>

Hope you understand it

And I hope my answer was of help to you.

Write the polynomial in standard form: 10x - 4 - 12x4 + x3
djyliett [7]
-12x^4 + x^3 + 10x - 4

To write in standard form means to order the terms in order of highest to lowest degree.

"Degree" means exponent. So in simpler words, you order the terms in order of descending exponent value. Ex: x^4 - x^3 + x^2...

Also, you write the terms with variables before the terms that are only a constant, which is why 10x comes before -4.
