Answer:

Step-by-step explanation:

In order to answer this question, you need to make an equation in the format of mx+b=y. This equation would look like this:

5x-12=48

Then, just solve for x. First, you would do the opposite of what your b is doing to both sides to move it. For instance, your b is being subtracted. So, add it to both sides to move it. It would then become:

5x=60

Then, you would do the opposite of what your m is doing to both sides to move it. So in this equation, you would divide both sides by 5. It would then give you:

x=12

Describe the steps in solving the linear equation 3(3x − 8) = 4x + 6.

Fittoniya [83]

Answer:

x=6

Step-by-step explanation:

3(3x-8)=4x+6

First you would distribute the 3 on the L side to the parenthasies

9x-24=4x+6

Then, you would subtract 4x from both sides because it is the smallest X value

5x-24=6

Add 24 to both sides (inverse operations)

5x=30

divide both sides by 5

x=6

The value of x is . I cant find any answers on this

GenaCL600 [577]

The angle that is next to 9x should be 180 - 9x because it is a straight angle.

Since there are 180 degrees in an angle we can add up the values to 180 and solve for x.

180- 9x + 5x + 9 + x = 180
-3x = -9
x = 3

Hope this helped!

To estimate the number of people in Springfield, population 10,000, who have a swimming pool in their backyard, 250 people were

Andrei [34K]

Answer:

2400 people

Step-by-step explanation:

Let x be the number of people who had a swimming pool in the population of 10,000,

Thus, the ratio of people who had swimming pool to the total population = $\frac{x}{10000}$

Since, out of 250 people 60 had swimming pool,

So, the ratio of the people who had swimming pool to the total population = $\frac{60}{250}$

$\because \frac{x}{10000}=\frac{60}{250}$

$\implies 250x=600000$

$\implies x=\frac{600000}{250}=2400$

Hence, 2400 people in the city might one expect to have a swimming pool.

First option is correct.

Which statement is true about the radical expression square root of 25

Lena [83]

Answer:

Step-by-step explanation:

The square Root of 25 in its simplest form means to get the number 25 inside the radical √ as low as possible.

25 is a perfect square, which means that you can simply calculate the square Root of 25 to get the answer. 5 times 5 equals 25. Thus, the square Root of 25 in simplest radical form is = 5
