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

Answer: x = 7

------------------------------

x + 11 = 18

x = 18 - 11

x = 7

Step-by-step explanation:

-k + 4(k + 1) = 2k

-k + 4k + 4 = 2k

-k + 4k - 2k = -4

(-1 + 4 - 2)k = -4

k = -4

Answer:

$10

Step-by-step explanation:

100% is $40

Every 25% is $10

So he has 25% or $10 left

Let X be a number of weeks, than you have

(60 + 7 * X) - ( 120 + 5 * X) = 0

Solve for X and you get X = 30 weeks

The key here is to recognize that when they both have equal amounts the difference between their amounts  will be 0c

Answer:

The turtle will go 18 miles in 90 minutes.

Step-by-step explanation:

6 divided by 30 = 0.2

0.2 x 90 = 18

18 miles

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:

y = x - 5

Step-by-step explanation:

(1,-4) and (2,-3)

Slope= (-3- - 4)/2-1) = 1/1 = 1

Point (1,-4)

y-intercept = y - (slope)(x)

y-intercept: -4 - (1)(1) = -4 -1 = -5

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 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 .

_________________

[tex]\boxed{\sf Step\: By\:Step:- }[/tex]

[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]
