Answer:

m=10

Step-by-step explanation:

9(m+5)−3(m−2)=8m+31

Step 1: Simplify both sides of the equation.

9(m+5)−3(m−2)=8m+31

9m+45+−3m+6=8m+31

(9m+−3m)+(45+6)=8m+31(Combine Like Terms)

6m+51=8m+31

Step 2: Subtract 8m from both sides.

6m+51−8m=8m+31−8m

−2m+51=31

Step 3: Subtract 51 from both sides.

−2m+51−51=31−51

−2m=−20

Step 4: Divide both sides by -2.

m=10

Hope this helps girly!!

What is 45,231 written in expanded form? 2 x 10,000 + 1 x 1,000 + 3 x 100 + 5 x 10 + 4 2 x 10,000 + 3 x 1,000 + 1 x 100 + 4 x 10

adoni [48]

Answer:

45231 = $4 \times 10000 + 5\times 1000 +2 \times 100 + 3\times 10 +1 \times 1$

Step-by-step explanation:

Given the number:

45,231

We have To write the given number in the expanded form.

Solution:

First of all, let us write the different digits of the number:

Unit's digit = 1

Ten's digit = 3

Hundred's digit = 2

Thousand's digit = 5

Ten thousand's digit = 4

Unit's digit has to be multiplied with 1.

Ten's digit has to be multiplied with 10.

Hundred's digit has to be multiplied with 100.

Thousand's digit has to be multiplied with 1000.

Ten Thousand's digit has to be multiplied with 10000.

And then they have to be added so that the number gets formed.

45231 = $4 \times 10000 + 5\times 1000 +2 \times 100 + 3\times 10 +1 \times 1$

for a class of 24,78% of students got a B or better on the tex How many students is this? Round to a wholenumber

natita [175]

Step 1

Use the ratio of the number to the percentage to get the required answer.

$\frac{Total\text{ number of students}}{\text{The required number of students}}=\frac{Total\text{ percentage of the class}}{\text{Given percentage}}$

Where,

$\begin{gathered} \text{The total number of students = 24} \\ \text{The required number }of\text{ students= x} \\ \text{The total percentage of the class = 100} \\ \text{Given percentage = 78} \end{gathered}$

Step 2

Get the required answer

$\begin{gathered} \frac{24}{x}=\frac{100}{78} \\ 100x=24\times78 \\ 100x=1872 \\ \frac{100x}{100}=\frac{1872}{100} \\ x=\text{ 18.72} \\ \text{Hence} \\ x\approx19students\text{ rounded to a whole number } \end{gathered}$

The number of students that got B or a better grade on the test = 19 students rounded to a whole number.

There is a 50% probability.

First add up all of the sections to get a total.

10 Green + 15 Purple + 2 Blue + 3 Red = 30.

There are 15 purple out of 30.

15/30 = 1/2 probability, which is 50%.

I need help with this problem I didn't really pay that much attention to this part of the subject.

Flauer [41]

To check if a piecewise defined function is continuous, you need to check how the pieces "glue" together when you step from one domain to the other.

So, the question is: what happens at x=3? If you reach x=3 from values slightly smaller than 3, you obey the rule f(x)=log(3x). So, as you approach 3, you get values closer and closer to

$\log(3\cdot 3)=\log(9)$

Similarly, if you reach x=3 from values slightly greater than 3, you obey the rule f(x)=(4-x)log(9). So, as you approach 3, you get values closer and closer to

$(4-3)\log(9)=\log(9)$

So, the function is continuous at x=3, because both pieces approach log(9) as x approaches 3.
