The answer is B, because 6x + 10x= 16x. So, the answer would be 16x-12y, which is your second step.

Answer:

option B is correct

Step 1. 6x - 12y + 10x

Step-by-step explanation:

Given the expression: \frac{2}{5} (15x-30y)+10x

Using distributive property:  a\cdot (b+c)=a\cdot b + a\cdot c

Apply distributive property in the given expression we get;

6x - 12y + 10x

Combine like terms;

16x - 12y

Now, factor a number means to break it up into numbers that can be multiplied together to get the original number

4\cdot 4x - 4 \cdot 3y

4(4x - 3y)

Therefore, the expression could be used  step 1 as,   6x - 12y + 10x

Three steps are:

Step 1. 6x - 12y + 10x

Step 2. 16x - 12y

Step 3. 4(4x - 3y)

A box contains 10 balls, of which 3 are red, 2 are yellow, and 5 are blue. Five balls are randomly selected with replacement. Ca
VLD [36.1K]

Answer:

The required probability is 0.1.

Step-by-step explanation:

red balls = 3

yellow balls =  2

blue balls = 5

Selected balls = 5

Number of elemnets in sample space = 10 C 5 = 1260

Ways to choose 1 red ball and 4 other colours =  (3 C 1 ) x (7 C 4) = 105

Ways to choose 5 balls of other colours = 7 C 5 = 21

So, the probability is

\frac{105}{1260} + \frac {21}{1260}\\\\\frac{126}{1260}=0.1
