Answer:

Step-by-step explanation:

-2x<-4

x=2

-2×2<-4

-4<-4

which is not true.

Hence x=2 is not a solution.

Answer: No

Step-by-step explanation: To determine whether x = 2 is a

solution to the inequality, substitute a 2 in for <em>x</em>.

So we have -2(2) < -4 or -4 < -4 which is a false statement.

No, 2 is not a solution to the inequality.

Travis has decided to budget his spending money. He can spend no more
Oxana [17]

x + 4.3x \leq 125.75 is the inequality that describes this problem

<h3><u>Solution:</u></h3>

Given that Travis can spend no more  than $125.75 every month

To find: linear inequality that describes the problem

Let the amount spent on movies = x dollars

Given that Travis decided to spend 4.3 times as much  money on video games as he spends on movies

Amount spent on video games = 4.3 (amount spent on movies)

Amount spent on video games = 4.3x

Travis can spend no more than $125.75.  That is, he can spend less than or equal to $125.75

<em><u>Thus, the inequality representing the situation is:</u></em>

\text{ Amount spent on movies + Amount spent on video games } \leq 125.75

x + 4.3x \leq 125.75

Thus the required inequality is found

Define mean. Then determine the mean of the following data set (22,18,38,6,24,18)
STALIN [3.7K]

Mean is the average number in the data set.

To get the average we first add all the numbers.

After we add all these numbers we then divide by the number of numbers in the data set.

So we do 22+18+38+6+24+18 which is equal to 126 there are six numbers so we divide 126 by 6. This gives us a mean of 21.

ANOTHER EXAMPLE:

Another example of this is the data set (4,65,7,34,5)

We first add all the numbers and get 115 then we divide by 5 and get 23 as the mean.
