[tex]\sf 3x-\left(2x-1\right)=7x-\left(3\times \:5x\right)+\left(-x+24\right)[/tex]

Remove the parentheses:

[tex]\to\sf 3x-\left(2x-1\right)=7x-3\times \:5x-x+24[/tex]

Combine like terms:

[tex]\sf ^*7x-x=6x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=6x-3\times \:5x+24[/tex]

Multiply 3 and 5x = 15x:-

[tex]\to\sf 3x-\left(2x-1\right)=6x-15x+24[/tex]

Combine like terms:

[tex]\sf ^*6x-15x=-9x[/tex]

[tex]\to\sf 3x-\left(2x-1\right)=-9x+24[/tex]

Expand: 3x-(2x-1)= x+1

[tex]\to\sf x+1=-9x+24[/tex]

Subtract 1 from both sides:

[tex]\to\sf x+1-1=-9x+24-1[/tex]

[tex]\to\sf x=-9x+23[/tex]

Add 9x to both sides:

[tex]\to\sf x+9x=-9x+23+9x[/tex]

[tex]\to\sf 10x=23[/tex]

Divide both sides by 10:

[tex]\to\sf \cfrac{10x}{10}=\cfrac{23}{10}[/tex]

[tex]\to\sf x=\cfrac{23}{10}[/tex]

Answer:

3/4<1/2<2/3

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

Remember PEMDAS

solve parentheses first : (2+2) = 4

Then multiply inside the brackets 4 x 5 = 20

20+5 = 25

Then multiply 2 x 25 = 50

50+5 = 55

Your answer would be 55

Answer:

(2,6)

Step-by-step explanation:

since DD is at (-2,6) and you're reflecting it just count 6 spaces from the point to the x-axis then go up 6 more the point will be at (-2,6) and if you go to the right 2 spaces to the y-axis then go two more you'll end up at (2,6)

The required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

Given that,
To find the products [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd].

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
Given expression,
= [1/5a²/b - 1/3c] × [-2/5ab - 1/6cd]
= 1/5a²/b[-2/5ab - 1/6cd]  - 1/3[-2/5ab - 1/6cd]
= -2/25a³b² - 1/60abcd +2/15ab + 1/18abcd
= -2/25a³b² + 2/15ab + 7/180abcd

Thus, the required product of the given expression is given as -2/25a³b² + 2/15ab + 7/180abcd.

Given set is A = {x:x+3 = 3 and x € N }

A is an empty set .

Reason :-

Put x = 1 then x+3 = 1+3 = 4

Put x = 2 then x+3 = 2+3 = 5

If we put x = 1,2,3...

We get { 4,5,6...}

So there is no natural number for x to get x+3 = 3

So ,There is no element to write for the set A

A is an empty set .

Note :-If x€W then x+3 = 0+3 = 3 then A is not an empty set .

If two ratios have the same value when simplified, then they are called Equivalent Ratios.

Equivalent ratios can be obtained by multiplying or dividing both sides by the same non-zero number.

As we want 3 equivalent ration in higher terms we will multiply it

4 : 7

by multiply with 2

4* 2 : 7* 2

8 : 14

by multiply with 3

4* 3 : 7* 3

2 : 21

4* 4 : 7* 4

16 : 28

Answer:

A: 0

Step-by-step explanation:

Important to remember - total displacement is the direct distance between the start and finish points, and isn't always equal to the total distance travelled.

In the case of the table above, the hiker travels the same distance in opposite directions, which actually means they cancel each other out! Traveling 4 km to the west, then 4 km to east means you end up in the same spot, right? So your total displacement is 0! (or 4 - 4, which equals 0). Same happens with the north-south hikes - the hiker ends up in the same spot, as the displacement is equal to 6 - 6 = 0.

So, the total displacement of the hiker is 0. (Even though the hiker travelled 20 km!)

The answer is 7

A tip you can do is get the sum subtract the number you do have so you would get your X value. So 18-11=7
