[tex]a(2x + 3) = 9x + 15 + x \\ a = \frac{5(2x + 3) }{2x + 3} \\ a = 5 \\ [/tex]

Hoor it helps

The solution of the given expression a(2x+3) = 9x+15+x is 5.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

Given the expression,

a(2x+3) = 9x + 15 + x

Divide both sides by 2x + 3

a = (9x + 15 + x)/(2x + 3)

a = (10x + 15)/(2x + 3)

a = 5(2x + 3)/(2x + 3)

a = 5

Hence "The solution of the given expression a(2x+3) = 9x+15+x is 5".

Answer:

61/50

Step-by-step explanation:

1*a = a

1 = b/b

then:

23*25 * 1 = (23/25)(12/12) = (23*12)/(25*12) =276/300

9/30 *1 = (9/30)(10/10) = (9*10)/(30*10) = 90/300

then:

(23/25) + (9/30) = (276/300) + (90/300)

= (276+90)/300

= 366/300

= 122/100

= 61/50

The addition of the fraction 23/25 + 9/30 is equal to 61/50.

A fraction represents a part of a number or any number of equal parts.

'a/b' of a quantity means that quantity is first divided in 'b' parts, and then mutiplied by 'a', or,

Once the denominators become same, the numerators can add up directly, giving us the final result of addition.

1*a = a

1 = b/b

then:

23*25 * 1 = (23/25)(12/12)

= (23*12)/(25*12) =276/300

9/30 *1 = (9/30)(10/10)

= (9*10)/(30*10) = 90/300

Now add the terms;

(23/25) + (9/30) = (276/300) + (90/300)

= (276+90)/300

= 366/300

Answer:

25 = 5^2

Step-by-step explanation:

Factor the following integer:

25

Hint: | Is 25 divisible by 2?

25 is not divisible by 2 since 25 is odd and 2 is even:

25 = 25 (25 is not divisible by 2)

Hint: | Is 25 divisible by 3?

The sum of the digits of 25 is 2 + 5 = 7, which is not divisible by 3. This means 25 is not divisible by 3:

25 = 25 (25 is not divisible by 2 or 3)

Hint: | Is 25 divisible by 5?

The last digit of 25 is 5, which means 25 is divisible by 5:

25 = 5 5:

25 = 5×5 (5 is not divisible by 2 or 3 since 25 is not)

Hint: | Now try to factor 5. Is 5 prime?

No primes less than 5 divide into it. Therefore 5 is prime:

25 = 5×5

Hint: | Express 25 as a prime power.

There are 2 copies of 5 in the product:

Step-by-step explanation:

3k +9 -k-17

Combine like terms

3k -k    +9-17

2k         -8

Answer:Simplifying

3k + 9 + -1k + -17 = 0

Reorder the terms:

9 + -17 + 3k + -1k = 0

Combine like terms: 9 + -17 = -8

-8 + 3k + -1k = 0

Combine like terms: 3k + -1k = 2k

-8 + 2k = 0

Solving

-8 + 2k = 0

Solving for variable 'k'.

Move all terms containing k to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + 2k = 0 + 8

Combine like terms: -8 + 8 = 0

0 + 2k = 0 + 8

2k = 0 + 8

Answer:  It does not lie on the line m.

Step-by-step explanation:

First using the slope and the point find an equation in slope intercept form and plot in the coordinates (82,63) to see if it fits. If it fits then it lies on line m and if doesn't then it doesn't like  on line M.

The slope intercept formula is   y = mx +b   where m is the slope and b is the y-intercept, so we need to use the coordinates (-2,1) to find the y-intercept.

Plot the coordinates and the slope into the formula to solve for b.

1 = 3/4(-2) + b

 1 = -6/4 + b    

+6/4 +6/4  

  b = 10/4  

y = 3/4x + 10/4

63  = 3/4(82) + 10/4  

63 = 64

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 74 in

The statement

The length of a rectangle picture is 5 inches more than three times the width is written as

l = 5 + 3w

Substitute the expression into the above formula and solve for the width

That's

74 = 2(5 + 3w) + 2w

74 = 10 + 6w + 2w

8w = 64

Divide both sides by 8

w = 8

Substitute this value into l = 5 + 3w and find the length

That's

l = 5 + 3(8)

l = 5 + 24

l = 29

The dimensions of the rectangle are

length = 29 inches

width = 8 inches

Answer:

[tex]x\geq 1[/tex]

B

Step-by-step explanation:

For square root functions, the domain is the restrictions on the x-variable.

Recall that you cannot take the square root of a negative. Thus, all values under the square root must be greater than or equal to 0. Thus, to find the domain, set the expression under the radical sign to greater than or equal to 0 and solve for x:

[tex](x-1)\geq 0[/tex]

Add 1 to both sides.

[tex](x-1)+1\geq 0+1\\x\geq 1[/tex]

Thus, the domain is:

[tex]x\geq 1[/tex]

All real numbers such that x is greater than or equal to 1.

Answer:

[tex]\huge \boxed{x \geq 1}[/tex]

Step-by-step explanation:

The domain of a function is all possible values for x.

There are restrictions on the value of x.

The number in the square root has to be greater or equal to 0 to be defined. Since the square root of a number lesser than 0 will be undefined.

[tex]x-1\geq 0[/tex]

Adding 1 to both sides.

[tex]x-1+1 \geq 0+1[/tex]

[tex]x\geq 1[/tex]

The domain of the function is [tex]x\geq 1[/tex]

All real numbers greater or equal to 1.
