Answer:

Step-by-step explanation:

The answer is 5 because as you can see: 10/8, if you divide the 10 by 2 that would be 5. Same with the denominator, 8 divided by 2 is 4. So, your answer is 5/4. Or 5.

Answer:

The answer is Y=5

Step-by-step explanation:

$\frac{y}{4} =\frac{10}{8}$

$y=\frac{10}{8}*4$

$y=\frac{10}{4*2}*4$ (8=4*2)

$y=\frac{10}{2}$

$y=5$

Option C:

$\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

To find which expression is equivalent to the given expression.

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}$

Using exponent rule: $\frac{1}{a^m}=a^{-m}, \ \ \frac{1}{a^{-m}}=a^{m}$

$$=\frac{-18 a^{-2} b^{5}a^{4} b^{6}}{-12 }$

$$=\frac{-18 a^{-2} a^{4} b^{5} b^{6}}{-12 }$

Using exponent rule: ${a^m}\cdot{a^n}=a^{m+n}$

$$=\frac{-18 a^{(-2+4)} b^{(5+6)}}{-12 }$

$$=\frac{-18 a^{2} b^{11}}{-12 }$

Divide both numerator and denominator by the common factor –6.

$$=\frac{3 a^{2} b^{11}}{2 }$

$$\frac{-18 a^{-2} b^{5}}{-12 a^{-4} b^{-6}}=\frac{3 a^{2} b^{11}}{2 }$

Therefore, $\frac{3 a^{2} b^{11}}{2 }$ is equivalent to the given expression.

Hence Option C is the correct answer.

|2w - 3| > 5 This is solving absolute value Inequalities. you through step by step?

dusya [7]

If |2w - 3| > 5

then

2w - 3 < - 5 or 2w - 3 > 5

2w < - 5 + 3 or 2w > 5 + 3

2w < - 2 or 2w > 8

w < -2/2 or w > 8/2

w < -1 or w > 4

So the solution set is

S = { x E R : w < -1 or w > 4}

or using the interval notation

S = (- infinity, -1) U (4, + infinity).

I hope this helps. =)
