Can advise on the solution?

Answer:

340

Step-by-step explanation:

If x is the amount of pages in the book we can write:

1/4x + 5 + 3/5(x - (1/4x + 5)) + 10 + 12 + 24 = x

1/4x + 51 + 3/5(3/4x - 5) = x

1/4x + 51 + 9/20x - 3 = x

7/10x + 48 = x

3/10x = 48

x = 160

It says to do 81^3/4 and i don’t know how to simplify that

scoundrel [369]

$\bf 81^{\frac{3}{4}}~~ \begin{cases} 81=&3\cdot 3\cdot 3\cdot 3\\ &3^4 \end{cases}\qquad \implies (3^4)^{\frac{3}{4}}\implies 3^{4\cdot \frac{3}{4}}\implies 3^1\implies 3$

What is the value of 12x^-3 y-1 for x=-1 and y=5 A.-12/5 B.-180 C.-60 D.-5/12

Mkey [24]

Expressions are mathematical statements represented with the variables

The value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5

<h3>How to determine the value of the variable</h3>

The expression is given as:

$12x^{-3} y^{-1}$

When x = -1, the expression becomes

$12 * -1^{-3} y^{-1}$

Evaluate the exponent

$- 12 y^{-1}$

When y = 5, the expression becomes

$- 12 * 5^{-1}$

Evaluate the exponent

- 12/5

Hence, the value of 12x^-3 y-1 for x=-1 and y=5 is - 12/5
