How do I solve this​
Gemiola [76]

Answer:

Step-by-step explanation:

Simplifying

f(x) = 800(0.85) * x

Multiply f * x

fx = 800(0.85) * x

Multiply 800 * 0.85

fx = 680x

Solving

fx = 680x

Solving for variable 'f'.

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

Divide each side by 'x'.

f = 680

Simplifying

f = 680

Find the mistake in the following : 3 x ( 4 + 2 ) = 12 + 2
Lyrx [107]

Answer: The mistake is improper use of distribution property.

Step-by-step explanation:

It is given that 3\times (4+2)=12+2.

We need to find the mistake.

The given expression is

3\times (4+2)

Using distribution property, we get

3\times (4)+3\times(2)

12+6

So, 3\times (4+2)=12+6.

In the given calculation the 3 is not distributed properly because 3 is not multiplied with 2.

Therefore, the mistake is improper use of distribution property.
