Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:
−
1

Figure that problem out then you will get -20.
Answer:
The fraction of Nathan's pencils that are yellow without erasers is 1/2.
Step-by-step explanation:
The problem gave us two informations, the first one is the fraction of the total amount of pencils that Nathan has that are yellow, the second one is the fraction of those yellow pencils that don't have erasers. So in order to find the fraction of the total pencils that are yellow pencils without erasers we need to multiply the two fractions that were given to us. So we have:
yellow pencils without erasers = (3/4)*(2/3) = 6/12 = 1/2
Answer
x=6, y=21/2
Explanation
The 86 degrees is just to make you confused.
Since this is a congruent triangle, you can just follow these steps.
Line AB: To get from 4 to 6, you multiply by 1.5.
Line BC: Divide 9 by 1.5 to get x. 9 divided by 1.5 is 6.
Line AC: Multiply 7 by 1.5 to get y. 7 times 1.5 is 10.5.
So the correct answer is the first choice; x=6, y=21/2 (this is also 10.5).
