Answer: x = 2/5 in fraction form
In decimal form, the answer is x = 0.4
====================================================
Work Shown:
2/3 = two thirds
2/3 + (1/3)x = 2x is the equation you're given
Multiply every term by 3 so that we clear out the fractions
3*(2/3) + 3*(1/3)x = 3*2x
2 + x = 6x
From here, we solve for x
2 + x = 6x
2+x-x = 6x-x .... subtract x from both sides
2 = 5x
5x = 2
5x/5 = 2/5 ... divide both sides by 5
x = 2/5
x = 0.4
Number one two and four are true
1. 3+5=8 and 8 is 80% of ten
2.the prob of drawing a red marble in the first go is 3/10 x 5/9 (for the probabilty of drawing a green one in the second go) =1/6
3. The probability OF drawing a blue marble is 20% (hence false)
4. 3+2 = 5, the same amount of red and blue marbles together as of green ones

Find 6% of $400 and add to $400.
6% of $400 =
= 6% * $400
= 0.06 * $400
= $24
6% of $400 is $24. That is the interest earned on $400 at 6% for 1 year.
Now we add it to the original amount, $400.
$400 + $24 = $424
Answer: $424
