Find the missing number of each unit rate. 155 = ?1 246 = ?1<br><br>worth 15 points!!!

alexgriva [62]

This is an incomplete question, the correct question is given below.

Find the missing number of each unit rate $\frac{15}{5}=\frac{?}{1}$ and $\frac{24}{6}=\frac{?}{1}$

Answer : The missing number of each unit rate of $\frac{15}{5}=\frac{?}{1}$ and $\frac{24}{6}=\frac{?}{1}$ are, 3 and 4 respectively.

Step-by-step explanation :

As we know that a unit rate is a rate in which 1 is present in denominator.

Or we can say that,

A unit rate is also called a single unit rate that means it will compare 1 unit of some quantity to a different units of a different quantity.

As we are given that that unit rates:

$\frac{15}{5}=\frac{?}{1}$ and $\frac{24}{6}=\frac{?}{1}$

Now we have to determine the missing number of each unit rates.

So, we can write the given expression as:

$\frac{15}{5}=\frac{?}{1}$

When are dividing 15 by 5, we get:

$\frac{15}{5}=\frac{3}{1}$

Thus, the missing number is, 3

And

$\frac{24}{6}=\frac{?}{1}$

When are dividing 24 by 6, we get:

$\frac{24}{6}=\frac{4}{1}$

Thus, the missing number is, 4

I really need help asap show all work

Triss [41]

Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

$-42k^3+24k^4+12k^5$

To find:

The factor form of the given expression.

Solution:

We have,

$-42k^3+24k^4+12k^5$

It can be written as:

$=6k^3(-7)+6k^3(4k)+6k^3(2k^2)$

Taking out the greatest common factor (GCF), we get

$=6k^3(-7+4k+2k^2)$

Therefore, the factor form of the given expression is $6k^3(-7+4k+2k^2)$ .

Answer:

A no solution

Step-by-step explanation:

y = 2x + 10

3y - 6x = 30

3(2x+10) -6x =30

6x +30 -6x =30

6x -6x = 30-30

0=0
