So to add fractions they need to have a common denominator, which in this case is 24. then multiply 1 by 4 and 5 by 3 because whatever you multiply the denominator by you need to do the same to the numerator, which will get you 4/24+15/24 then you add across the numerators and you get 19/24
Combining like terms is pretty simple. First, you would identify which terms are similar to what terms. For example, you can't combine two terms that aren't similar like 2x and 3y. It would have to be 2x and 3x to combine. Next, be sure to add/multiply/subtract/divide/etc. the terms. For example, if you had the problem 2x + 4x + 3y, you would combine the "x" terms and the resultant problem would be 6x + 3y. Hope this helped :)
Answer:
A. One solution
Step-by-step explanation:
To find out, we solve the equation.
6 - 3x = 12 - 6x
Add 6x to both sides. Subtract 6 from both sides.
3x = 6
Divide both sides by 3.
x = 2
Answer: A. One solution
There are 10 marbles, out of these 10 there are 4.
The probability of her picking a blue marble is 4/10
This can be simplified to 2/5
