Answer:

Simplification of the given expression gives value of x = 24.

Step-by-step explanation:

Here, the given expression is  3(x-4)+5x=9x-36

Now, by DISTRIBUTIVE PROPERTY:

A ( B - C )  =  AB  -  AC

Simplifying the given expression step by step ,we get:

3(x-4)+5 x = 9 x - 36  ⇒     3(x) - 3(4) + 5x = 9x - 36

or, 3x - 12 + 5x = 9x - 36

⇒ 8x - 9x = -36 + 12

or, - x  = - 24

⇒ x  = 24

Hence, the the simplification of the  given expression, the value of x = 24.

Step-by-step explanation:

(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12

__

You can also work this using improper fractions:

(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)

  = (11×5)/(6×2×5) = 11/(6×2) = 11/12

kow [346]

Answer:

d. An additional month of buying and selling is associated with an additional $417 in profits.

Step-by-step explanation:

We have general form of intercept form of equation:

y = m*x + c ----- (A)

Given equation is : y = 2502 + 417*x

Rewrite equation: y = 417*x + 2502 ------(B)

comparing equation (B) with equation (A), we get

m = 417 (additional benefits per month) because multiplied factor x is the month.

Answer:

700,000

Step-by-step explanation:

To explain this, we need to know the basics.

If you look at the number 790,390, you should automatically know that you can also write the same number as:

700,000 + 90,000 + 300 + 90

How did we do this?

Because each number in 790,390 has a <u>value.</u>

In fact, we can do this for any number! Like this:

12,345

You can also write the same number like this:

10,000 + 2,000 + 300 + 40 + 5

Back to the original question. If there is a seven in the hundred thousands place, that means that the 9 is equal to 700,000

Examples:

12,345

The 3 in this number stands for 300, since it is in the hundreds place.

678,900

The 7 in this number stands for 70,000 because it is in the ten thousands place

Now you know!
