Answer:
0.5
Step-by-step explanation:
If there are twenty white marbles in a bag of 40, then the chances of drawing a white marble is 20/40, or 0.5: one chance in two of drawing white.
To add expressions, you should take note that you can only
combine same terms which means they have the same degree of exponents.
-5x^4 + 6x^3 – 43 + 6x^5 – x^2 + 12x + 12
In this expression, you can only combine the constants
because they are the only similar terms:
-5x^4 + 6x^3 + 6x^5 – x^2 + 12x + 12 – 43
-5x^4 + 6x^3 + 6x^5 – x^2 + 12x – 31
The standard form starts with the term with the highest
exponent so you just have to arrange the terms:
6x^5 - 5x^4 + 6x^3 – x^2 + 12x + 12
Step-by-step explanation:
2x - 5 = 7
2x = 7 + 5
2x = 12
x = 12 / 2
x = 6
