Reduce the Fraction: a(x-2y)/b(2y-x)

Answers

Answer:

[tex]\displaystyle-\frac{a}{b}[/tex]

Step-by-step explanation:

We have:

[tex]\displaystyle{\frac{a(x-2y)}{b(2y-x)}[/tex]

In the denominator, we can factor out a negative 1. This yields:

[tex]=\displaystyle\frac{a(x-2y)}{-b(x-2y)}[/tex]

We can now cancel out the factor. Hence:

[tex]\displaystyle=-\frac{a}{b}[/tex]

A rectangular tank has length 4m, width 12m and height 3.5..i. If the tank is filled with water 2/3 of its capacity ,calculate the volume of the water in the tank.​

Answers

Answer:

The volume of the water in the tank is 112 m³

Step-by-step explanation:

The volume of the rectangular prism V = L × W × H, where

L is its lengthW is its widthH is its height

∵ A rectangular tank has a length of 4 m, a width of 12 m, and

   a height of 3.5 m

∴ L = 4 m

∴ W = 12 m

∴ H = 3.5 m

∵ V = L × W × H

∴ The volume of the tank = 4 × 12 × 3.5

∴ The volume of the tank = 168 m³

∵ The tank is filled with water  [tex]\frac{2}{3}[/tex] of its capacity

→ That means the volume of the water is  [tex]\frac{2}{3}[/tex]  the volume of the tank

∵ The volume of the water = [tex]\frac{2}{3}[/tex] the volume of the tank

∴ The volume of the water =  [tex]\frac{2}{3}[/tex] × 168

∴ The volume of the water = 112 m³

∴ The volume of the water in the tank is 112 m³

​

Answers

Answer:

Option A: 11,1 is the correct answer.

Step-by-step explanation:

The absolute value is used in the given expressions.

The absolute value represents the values of a number or variable irrespective of its sign. This means that |x| = x and |-x| = 0

Given expression is:

[tex]|2x-5|[/tex]

Putting x=3

[tex]|2(-3)-5| \\= |-6-5|\\= |-11|\\=11[/tex]

Putting x=-3

[tex]|2(3)-5| \\= |6-5|\\= |1|\\=1[/tex]

Hence,

Option A: 11,1 is the correct answer.

3 divided by 1/? = 18

Answers

Answer: ? = 6

Step-by-step explanation:

3 divided by 1/x = 18

3x= 18

x = 6

Answer:

3 divided by 1 equals 3

How :

We can write 3 divided by 1 as a ratio, fraction, or equation. Let's try writing this statement in all these ways

3:1

3/1

3÷1

The easiest way for me to solve this question is as a fraction so let's solve it like that. If the denominator is a 1, we immediately know that the answer is the numerator and that you don't need the denominator. so we can take away the 1 from 3/1 and that is how our answer is 3!

Hope this Helps!!! :)
