18 - t/20= -9 what does t equal?

18 - t/20 = -9 what does t equal?

Answer:

t = 540

Step-by-step explanation:

18 - t/20 = -9

Subtract 18 from both sides.

-t/20 = -27

Multiply both sides by -20.

t = 540

What is the difference of the polynomials? (x4+x3+x2+x)-(x4-x3+x2-x)

(x^4 + x^3 + x^2 + x) - (x^4 - x^3 + x^2 -x)

x^4 + x^3 + x^2 + x - x^4 + x^3 - x^2 + x

2x^3 + 2x

x^4 + x^3 + x^2 + x - x^4 + x^3 - x^2 + x

2x^3 + 2x

Answer:

Difference of the polynomial is;

Step-by-step explanation:

Given the expression:

Remove parenthesis, distributing negative sign we have;

Combine like terms, and wrote in decreasing order of the exponents.

Therefore, the difference of the given polynomial is;

Write an expression to represent: The sum of ten and the quotient of a number x and 6.

Let us break it down. A sum of ten. That is just

+10

Then, we will add that to the quotient (which is the number after dividing) of a number x and 6. We can write that as

+ x/6

The slash means division here. Thus your final answer is

10 + x/6

+10

Then, we will add that to the quotient (which is the number after dividing) of a number x and 6. We can write that as

+ x/6

The slash means division here. Thus your final answer is

10 + x/6

Which expressions are equivalent to (k^(1/8))^(−1) ? choose all answers that apply:

a. (k^(-1))^(1/8)

b. (8_/`k)^(-1)

c. k^(-1/8)

d. none of the above

* _/` is a radical with 8 as the index and k as the radicand

The first option is correct: we have

The second option is also correct, because it simply applies the definition

The third option is also correct, because it applies the rule
