Answer:

x = 36

Step-by-step explanation:

180 - 126 = 54

90 + 54 + x = 180

144 + x = 180

180 - 144 = x

x = 36

Have a nice day!

If x varies inversely as y 2, and x = 2 when y = 20, find x when y = 5.

Dominik [7]

Step-by-step explanation:

$x = \frac{k}{y}$

x varies inversely as y. This means that x is equal to the inverse of y which can be translated as x = 1/y but the problem said that x is not exactly equal to the inverse of y. Therefore, we need to introduce a factor k. Factor k will represent the word "varies" in the problem.

To illustrate:

$x = \frac{k}{y}$

Since we don't have the value of k, we have to solve for it by using the first values of x and y which was given as x=2 and y=20.

$x = \frac{k}{y} \\ 2 = \frac{k}{20} \\ k = 2(20) = 40$

Now that we have the value of k, we can now solve for the value of x when y=5.

$x = \frac{k}{y} \\ = \frac{40}{5} \\ = 8$

Therefore, when y is 5, the value of x is 8.

Can someone explain the steps to simplify x^4/3 over x^5/6 and how to simplify 16 square root of x * x^3 * x^4 (AGAIN EXPLAIN IN

slavikrds [6]

Remember
(x^m)/(x^n)=x^(m-n)

(x^4/3)/(x^5/6)=
x^(4/3-5/6)=
x^(8/6-5/6)=
x^(3/6)=
x^(1/2)

second one
16 times the square root of x*x^3*x^4
first simpify parenthasees
remember
(x^m)(x^n)=x^(m+n)
(x^1)(x^3)(x^4)=x^(1+3+4)=x^8

√x^8 aka
√(x^4)^2
is x^4

16x^4 is ansre√
