Write 4x24 as distributive property

Answers

Let's check the distributive property first :

$a(b+c)=ab+ac$

where $a$ , $b$ , and $c$ are real numbers.

Now, to express 4x24 in the form $a(b+c)=ab+ac$ , we just need to express 24 as a sum or subtraction.

Notice that we can express a 24 as a sum or subtraction in a number of ways:

1. 24-12=12, so 12+12=24

2. 24-10=14, so 10+14=24

3. 28-4=24, so 28-4=24

And so on...

Now let's use the distributive property:

1. $4*24=96$

Since 24=12+12, we can express the same multiplication using the distributive property as:

$4(12+12)=4*12+4*12=48+48=96$

2. $4*24=96$

Since 24=10+14, we can express the same multiplication using the distributive property as:

$4(10+14)=4*10+4*14=40+56=96$

3. $4*24=96$

Since 24=28-4, we can express the same multiplication using the distributive property as:

$4(28-4)=4*18-4*4=112-16=96$

As you can see, there are many ways to use the distributive property.

4 x 24 =

4 x 20 = 40
4 x 4 = 16

40 + 16 = 56
4 x 24 = 56

Paige was assigned some math problems for homework. She solved the first 32 of the problems before dinner. She finished the last 20% of the assignment after dinner. How many math problems was Paige assigned

Paige was assigned 40 math problems.

What is an expression?

An expression is a combination of numbers, variables, and operators that represents a mathematical quantity or relationship. Expressions do not contain an equals sign (=) and are not true or false statements. Instead, expressions are evaluated to produce a value or another expression.

Let's call the total number of math problems Paige was assigned "x".

Paige solved the first 32 problems, so she still had to solve x - 32 problems after dinner.

We know that she finished the last 20% of the assignment after dinner, which means she solved 80% of the problems before dinner.

80% of x can be written as 0.8x.

So, the equation we can set up is:

x - 32 = 0.2x

Solving for x, we get:

0.8x = 32

x = 40

Therefore, Paige was assigned 40 math problems.

80% of all problems=32 problems.
x=total number of problems.
We can suggest this equation:
80% of x=32
(80/100)x=32
x=(32*100)/80=40
