What is the value of a in the equation 3 a plus b equals 54 when b equals 9?

Answers

Answer:-1/3b+18

Step-by-step explanation:

Let's solve for a.

3a+b=54

Step 1: Add -b to both sides.

3a+b+−b=54+−b

3a=−b+54

Step 2: Divide both sides by 3.

3a/3=  -b+54

Answer:

√110

Step-by-step explanation:

The multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The number expression is:

=  √2. √5 . √11

From the definition of the arithmetic operation, the operation in which we do the addition of numbers, subtraction, multiplication, and division.

= √(2x5x11)

=  √110

Thus, the multiplication of the numbers √2, √5, and √11 is √110 after applying arithmetic operation.

Answers

Answer:

1.) X = 1     2.) X = 7

Step-by-step explanation:

1.) 3x - 6 = 9

Subtract 6 on both sides

3x = 3

Divided 3 on both sides

X = 1

2.) -5x + 3x = 11 + 3

Put the like terms on both sides

-2x = 14

Divide both sides by 2

X = 7

"what value of x makes 5x+10=5(11-2x)

Answers

Answer:

5x + 10 = 5(11 - 2x)

5x + 10 = 55 - 10x

5x + 10x = 55 - 10

15x = 45

15x ÷ 15 = 45 ÷ 15

x = 3

how do u evaluate variable expression ​

Answers

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression. Hope this helps! :)

The sum of 5 consecutive numbers is 70. Determine the value of the smallest number.

Answers

Answer:  12

==========================================================

Work Shown:

x = first number

x+1 = second number

x+2 = third number

x+3 = fourth number

x+4 = fifth number

Note how the numbers are one after another. Consecutive numbers follow this pattern. For example: 6,7,8,9,10 are consecutive numbers. One number follows right after the other.

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

Add up those five expressions. Set the sum equal to 70 and solve for x

(x)+(x+1)+(x+2)+(x+3)+(x+4) = 70

(x+x+x+x+x)+(1+2+3+4) = 70

5x+10 = 70

5x = 70-10

5x = 60

x = 60/5

x = 12 is the first number and the smallest number

x+1 = 12+1 = 13 is the second number

x+2 = 12+2 = 14 is the third number

x+3 = 12+3 = 15 is the fourth number

x+4 = 12+4 = 16 is the fifth number

Check:

12+13+14+15+16 = 70

which confirms our answer

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

You could use a guess and check method, but the algebraic approach is much more efficient.

Answers

Answer:

24x^2 -10x - 25

Step-by-step explanation:

24x^2 + 20x - 30x - 25

24^2 -10x - 25

Answer:

Simplifying

4x + -5 = 6x + 5

Reorder the terms:

-5 + 4x = 6x + 5

Reorder the terms:

-5 + 4x = 5 + 6x

Solving

-5 + 4x = 5 + 6x

Solving for variable 'x'.

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

Add '-6x' to each side of the equation.

-5 + 4x + -6x = 5 + 6x + -6x

Combine like terms: 4x + -6x = -2x

-5 + -2x = 5 + 6x + -6x

Combine like terms: 6x + -6x = 0

-5 + -2x = 5 + 0

-5 + -2x = 5

Add '5' to each side of the equation.

-5 + 5 + -2x = 5 + 5

Combine like terms: -5 + 5 = 0

0 + -2x = 5 + 5

-2x = 5 + 5

Combine like terms: 5 + 5 = 10

-2x = 10

Divide each side by '-2'.

x = -5

Simplifying

x = -5
