Hi there!
Let's simplify step by step.


2y(3 - x) + 7(x - 2y) =
First we work out the parenthesis (for instance possible by using rainbow technique).

2y \times 3  +  2y \times -  x + 7 \times x + 7  \times  - 2y = \\ 6y - 2xy + 7x - 14y =
Finally we collect the common terms.

- 2xy + 7x - 8y
~ Hope this helps you!

The first step for solving this expression is to distribute 2y through the first parenthesis.
6y - 2xy + 7(x - 2y) 
Now distribute 7 through the second set of parenthesis.
6y - 2xy + 7x - 14y
Lastly,, collect the like terms with y.
-8y - 2xy + 7x
Since we cannot simplify any further,, -8y - 2xy + 7x is the correct answer to your question.
Let me know if you have any further questions.

Determine which numbers could not be used to represent the probability of an event. Select all that apply. A. StartFraction 64 O
vova2212 [387]

Answer:

A. \frac{64}{25} ​, because probability values cannot be greater than 1.

C. -1.5, because probability values cannot be less than 0.

Step-by-step explanation:

Probability is the extent to which an event is likely to happen. It ranges from 0(impossible) to 1(certain). Probability values can be written in decimal form or in fractional form.

The following numbers could not be used to represent the probability of an event.

A. \frac{64}{25} ​, because probability values cannot be greater than 1.

C. -1.5, because probability values cannot be less than 0.

Find the measure of one interior angle for the following regular polygon ​
kipiarov [429]

Answer:

144 degrees

Step-by-step explanation:

We can use the formula (n-2)(180), where n = number of sides, to find the sum of all the interior angles in the decagon. Since a decagon has 10 sides:

(n-2)(180) = ?

(10-2)(180) = ?

(8)(180) = 1440.

Now, to find one interior angle in the decagon, divide 1440 by the number sides in our polygon (10).

1,440/10 = 144

               = <u>144 degrees</u>

The Hamilton Brush Company issued 2,500 shares of common stock worth $100,000.00 total. What is the par value of each share?
alexandr1967 [171]
What we know here is that all 2500 shares together are worth 100 000 dollars in total. (it's 100 000.00 actually, but we can ignore the part after the point, as it's equal to 0).

This means that each of the shares is valid the whole sum divided by the number of shares, that is:
\frac{100000}{2500} = \frac{1000}{25} =40
(first i divided both denominator and numerator by 100)
So each value is worth 40 dolars.
