How many solutions can be found for the equation 5x + 3(x − 1) = 10x − x − 5? (4 points)

a
No Solution

b
One

c
Two

d
Infinitely many

Answers

Answer:

The correct option is b.

Step-by-step explanation:

To find the number of solutions, we need to solve the equation:

[tex] 5x + 3(x - 1) = 10x - x - 5 [/tex]

Let's group all the "x" on the equation.  

[tex] 5x + 3x - 10x + x = 3 - 5 [/tex]              

Now, let's solve for "x".

[tex] -x = -2 [/tex]                

[tex] x = 2 [/tex]    

Therefore, the equation has one solution. The correct option is b.

I hope it helps you!

Answers

Answer:

1. 25

2. 24

equations below

Step-by-step explanation:

Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction

1. 5 x (20/4)

normally we multiply before we divide, but in this case, the division is in parentheses, so we start there

= 5 x 5

then multiply

= 25

------------------------

2. The lovely land of exponents

6^2 (the only way I can type 6 squared, or 6 to the power of 2, where the 2 is up as a superscript)

6^2 - 2 x 6

PEMDAS has us do the exponents before multiplication or subtraction:

6^2 = 6 x 6 = 36

= 36 - 2 x 6

then multiply:

= 36 - 12

then subtract:

= 24

In the figure below, DF is a straight line. What is the degree measure of <FEG?​

Answers

Answer:

c. 56 degrees

Step-by-step explanation:

angle FEG and angle DEG add up to 180.

2x-6+3x-31=180

x=31

2(31)-6=56

The measure of angle ∠ FEG is,

∠ FEG = 56°

We have to given that,

Angles are defined as,

∠ FEG = (2x - 6)°

∠ DEG = (3x + 31)°

Here, Angles FEG and angle DEG are linear pair.

Hence, angle FEG and angle DEG add up to 180.

2x - 6 + 3x + 31 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155 / 5

x = 31

Therefore, The measure of angle ∠ FEG is,

∠ FEG = (2x - 6)°

∠ FEG = (2 × 31 - 6)°

∠ FEG = (62 - 6)°

∠ FEG = 56°

Which graph represents y as a function of x

Answer:

there is no gragh

Step-by-step explanation:

Every ten years, the Census counts how many people are living in every town in
the United States.
The 2010 Census showed that 1,000 people were living in Appleville,
and 4,000 people were living in Bridgetown.
The population of Appleville is predicted to double every ten years.
The population of Bridgetown is predicted to increase by 1,000 every
ten years.
If the predictions come true, what will be the first census year that will show
Appleville with a larger population than Bridgetown?

Answers

Answer:

2040

Step-by-step explanation:

We know Appleville is predicted to double its population every 10 years, while Brigdetown simply adds 1000. Doing the math, the 2040 Census will be the first one where Appleville's population (8,000) will be larger than Bridgetown's (7,000).

Appleville: 1,000 * 2³ = 1,000 * 8 = 8,000 people in 2040

Bridgetown: 4,000 + 3(1,000) = 4,000 + 3,000 = 7,000 people in 2040

8,000 > 7,000, so 2040 will be first census year where Appleville is larger than Bridgetown. (I know this is extra, but if this was asking for first year overall, then it would be 2037. 6,800 > 6,600)
