The solution of the given expression is 63.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Here the given expression is :

3(a-2b)

where, a = -3

and, b = -12

Now, substitute the value of a and b in the given expression :

3(a-2b)

= 3(-3-2x -12)

= 3(-3 + 24)

= 3(21)

= 63

Therefore, the solution of the given expression is 63.

Step-by-step explanation:

option B is correct

a/q

→ 8(1/10) + 7(1/100) + 1(1/1000)

can be written as

→ 8(0.1) + 7(0.01) + 1(0.001)

→ 0.8 + 0.07 + 0.001

→ 0.871

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

B. 0.871

Step-by-Step:

First multiply eight by one tenth = 8 x 0.1= 0.8

Then multiply seven by one hundredth= 7 x 0.01= 0.07

Then multiply one by one thousandth= 1 x 0.001= 0.001

Then add them all, 0.8+0.07+0.001 = 0.871

Explain why 0 divided by any number is either 0 or infinity.

Answers

Step-by-step explanation:

Division as the inverse of multiplication

But any number multiplied by 0 is 0 and so there is no number that solves the equation. ... In general, a single value can't be assigned to a fraction where the denominator is 0 so the value remains undefined.

Answer:

0 divided by itself is undefined so we use infinity or 0 to describe it because infinity has no limits and it doesn’t really exist so I wouldn’t say it equals infinity or 0 but it is undefined. I hope it helps! Let me know if you need more help :D

The length of a side of a square is given by the expression 2 +1, and its perimeter is 56.

Write and solve an equation to determine the value of x.
Calculate the length of a side of the square.

Answers

Answer:

x = 13/2

Step-by-step explanation:

the perimeter of the square = 4 (2x + 1) = 56 → (solve for x)

divide both sides by 4

2x + 1 =56/4 = 14

2x = 14 - 1 = 13 ⇒ x = 13/2

Answer:

a = 14

Step-by-step explanation:

2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4

3.Multiple: 6 * 6 = 36

4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40

5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000

6.Divide: 9 / 3 = 3

7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003
