Answer:
1/64
Step-by-step explanation:
When you simplify the expression, its fraction form is 1/64
E+S+Y=68
E=S/2
S=Y-3
E=(Y-3)/2
E+S+Y=68
(Y-3)/2+Y-3+Y=68
(Y-3)/2+2Y-3=68
(Y-3)/2+2Y=71
(Y-3)/2+4Y/2=71
Y-3+4Y/2=71
5Y-3=142
5Y=145
Y=145/5
Y=29
Answer:

Step-by-step explanation:
Let's first write the expression:

Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.

Now we combine like terms.

Write the polynomials by decreasing exponents

Triangle ABC because the other ones are different from each other and there is only one of them.
