Can someone help me please!!

Answer:

We conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

Step-by-step explanation:

A.

10x + 2x = (10 + 2)x - 2

Checking the equation in Part A

10x + 2x = (10 + 2)x - 2

10x + 2x = 10x+2x-2

10x + 2x - 10x - 2x = -2

0 = -2

The sides are not equal.

Hence, NO SOLUTION!

B.

10x + 2 = (10 + 2)x - 2x

Checking the equation in Part B

10x + 2 = 10x+2x - 2x

10x + 2 - 10x - 2x + 2x = 0

2 = 0

The sides are not equal.

Hence, NO SOLUTION!

C.

10x + 2x = (10 + 2)x

Checking the equation in Part C

10x + 2x = 10x+2x

10x + 2x - 10x - 2x = 0

0 = 0

Both sides are equal.

It is true for all x.

D.

10x + 2 = (10 + 2)x

Checking the equation in Part D

10x + 2 = 10x+2x

10x - 10x - 2x = -2

-2x = -2

Divide both sides by -2

x = 1

Hence, 10x + 2 = (10 + 2)x has only 1 solution.

Therefore, we conclude that  10x + 2 = (10 + 2)x has only 1 solution.

Hence, option (D) is correct.

Answer:ok so yes the answer is the one you selected because 25.00 devided by 2.50 is 10 and 5 devided by 25 is 5 or you could go like 2.50 times 10 is 25 and 5 times 5 would be 25

Answer:

Step-by-step explanation:

because it needs to be a number times itself to be be a perfect square

Answer:

The square root of 64 gives the original number. If you square 8, you get 64, making it a perfect square. However, 60's square root is only approximate to 60 and very close to it when squared. Therefore, it cannot be a perfect square.

Answer:

140

Step-by-step explanation:

420/15=28

28x5=140

This number is greater than our solution to 1.11 * 10^12.

What are exponent and examples of them?

First we need to find the value of 1.11 * 10^12.

We need to solve the exponent first.

10^12 = 1000000000000

Next, we will multiply this by 1.11.

1,000,000,000,000 * 1.11 = 1,110,000,000,000

The value of 1.11*10^12 is equal to 1,110,000,000,000.

We can immediately rule out a), 90,000,000,000 as an answer. We can easily tell that out solution is greater than this answer.

Now we will find the value of option b).

5.66 * 10^11.

We need to solve the exponent first.

10^11 = 100000000000

Next, we will multiply this by 5.66.

100,000,000,000 * 5.66 = 566,000,000,000

This number is not greater than our solution to 1.11 * 10^12. Therefore, option b) is not your answer.

Now we will find the value of option c).

1.01 * 10^13.

We need to solve the exponent first.

10^13 = 10,000,000,000,000

Next, we will multiply this by 1.01.

10,000,000,000,000 * 1.01 = 10,100,000,000,000

This number is greater than our solution to 1.11 * 10^12. Therefore, option c) is your answer.

Answer:

I don't know if I'm correct but the answer is 6.

Step-by-step explanation:

I'm not 100% correct, but you set the other two angles to add to each other then set it equal to angle QRS and i got x=6.

Your equation should be like this: 3x + 17 + 2x +21 = 10x -1

than you solve form there

I;m not sure that this is the correct answer and maybe i'm wrong, but hope this helps

Answer:

59°

Step-by-step explanation:

According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]

So, by exterior angle property of a triangle, we have:

[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\

(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\

(10x - 1)\degree = (3x +17+2x +12)\degree\\\\

(10x - 1)\degree = (5x +29)\degree\\\\

(10x - 1)= (5x +29)\\\\

10x - 5x = 29 + 1\\\\

5x = 30\\\\

x = \frac{30}{5}\\\\

x = 6\\\\

\because m\angle QRS = (10x - 1)\degree \\\\

\therefore m\angle QRS = (10\times 6- 1)\degree \\\\

\therefore m\angle QRS = (60- 1)\degree \\\\

\huge\orange{\boxed{\therefore m\angle QRS = 59\degree }}\\

Always start on the y-axis.

rise/run

First things first, you have to know your positives, negatives, zeros, and undefined.

To make an equation from the graph you have to know your formula.

y=mx+b

You do the rise first. The rise on the graph is 3. The run is 2. So, that'll make it 3/2. m=slope.

b=y-axis. b=1.

y=3/2x+1 (Example from the image)

Answer:

-1 5/6

Step-by-step explanation:

-2/3 + (-1 1/6)

Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.

Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.

-2/3 * 2/2 = -4/6

-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.

Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.

Answer: -2/3 + (-1 1/6) = -1 5/6

Answer: 131

Step-by-step explanation:

The angle A inside the triangle is

180-162 = 18 degrees

The measure of angle N inside the triangle is

180 -  149 = 31 degrees

Now, since we have the inside angles we can find ang P

Inside Ang A + Inside Ang N + Ang P = 180

18 + 31 + P = 180

49 + P = 180

P = 180 - 49

P = 131 degrees

C is the answer √(8^3)

The initial value for the root is 2 and it doesn't need to be written so 8^3/2

It is found that location of Sam's house is at a distance of approximately 8.062 meters far from the gas station.

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]  

Sam's house S(x, y) = (2, -4)

Library L(x, y) = (-5 , 2)

Gas station  G(x, y) = (3, 4)

The distance d, in miles, is determined by the line segment distance formula:

D = √[(x-p)² + (y-q)²]  

It is used in an operation known as dot product.

Then the distance between Sam's house and the Gas station is:

D = √[(2 - 3)² + (-4 -4)²]  

D = 8.062 meters

Hence, The location of Sam's house, is at a distance of approximately 8.062 meters far from the gas station.
