Hey!

Let's solve this together.

5x+1 = 1+x2

Possible Answers: {5,4,3,2}

Lets start with 5.

5(5)+1 = 1+2(5)***

25+1 = 1+10

26 ≠ 11

So, 5 is NOT the answer.

Now, 4.

5(4)+1 = 1+(4)2

20+1 = 1+8

21 ≠ 9

So, 4 is NOT the answer.

Now, 3.

5(3)+1 = 1+(3)2

15+1 = 1+6

16 ≠ 7

So, 3 is NOT the answer.

Lastly, 2.

5(2)+1 = 1+(2)2

10+1 = 1+4

11 ≠ 5

So, 2 is NOT an answer.

So, the answer is: None of the above. None of them can be answers because none of them make the statement true.

***(In algebra, we start using parenthesis instead of the dot for multiplication when using numbers.)

Hope this helps!

Anyoneee?? Mean Median and mode
juin [17]

Answer:

mode is the most occuring number which is in this case 11

you get the median by putting them in order from least to greatest and them marking them out until you get to the middle but if there are two numbers in the middle you add them and then divide by two and that is your median but in this case your median is 11

you get the mean by adding all the numbers together and dividing by how many numbers there are so in this case you are dividing by 9 and when you add oall of these numbers together you get 98 and 98/9 is 10.8888888889 which you would round and get 10.9

hope this helps

The Montanez family is a family of four people. They have used 3,485.78 gallons of water so far this month. They cannot exceed 7
il63 [147K]

Answer:

x ≤ 3764.72

Step-by-step expl anation:

The Montanez family cannot use more than 7250.50 gallons, this means that they can use less than or equal to 7250.50 gallons, this tells you which sign to use.  The variable x can be used to describe how much water they have left to use and then you add 3,485.78 gallons to x.

x + 3485.78 ≤ 7250.50   This inequality means that the amount of water the family has yet to use added to 3485.78 gallons cannot exceed 7250.50 gallons.

Next, you simplify the inequality using the property of inequalities.

x ≤ 7250.50 - 3485.78

x ≤ 3764.72

Plzz help me with this question
bixtya [17]

Answer:

x = 5

Step-by-step explanation:

We need to find the value of x in this case.

For this, we need to consider that the triangles are similar. Now, we can find it as follows :

\dfrac{12}{3}=\dfrac{20}{x}\\\\x=\dfrac{20\times 3}{12}\\\\x=5

So, the value of x is equal to 5.
