12 3/4 + 5 = 17 3/4 since you only have to add the whole numbers
same for subtraction
12 3/4 - 5 = 7 3/4
If you mean to say to find the 11th term, then know that this is an arithmetic sequence (where you have a common difference).
The common difference in this case is -2.
The formula for finding any term in an arithmetic sequence (specifically the explicit formula) is:
where a_n is the term, a_1 is the first term, n is the term number (position) and d is the common difference.
Let's substitute the corresponding values to the formula.
The 11th term is -17.

Step-by-step explanation:
Answer:
C.
Step-by-step explanation:
When we have an expression where the a number with an exponent is raised to another power, we simply apply one of the laws of exponents known as the power rule.
The rule says we just simply multiply the exponents together.
Thus,
Therefore, the expression given, where we need to apply this rule is:
The answer is C.
ax+by=c
move ac to the other side
sign changes from +ax to -ax
ax-ax+by=c-ax
by=c-ax
divide both sides by y
by/y=c/y-ax/y
Cross out y and y then becomes 1*1*b=b
Answer"
b=c/y-ax/y
