5x + 4y = 2
-5x - 2y = 4

So if we add both the equations 5x will be eliminated.

5x + 4y - 5x - 2y = 4 + 2
4y - 2y = 6
2y = 6
y = 3

As y is 3

x will be
5x + 4 x 3 = 2
5x + 12 = 2
5x = -10
x = -2

The mean of the data is 18. What number is missing? 21,11,_,27,22,13,16
Ludmilka [50]

The missing number is 16

<em><u>Solution:</u></em>

Given that mean of data is 18

Let "x" be the missing number

The data set is:

21, 11, x , 27, 22, 13, 16

Sum of data set = 21 + 11 + x + 27 + 22 + 13 + 16

Sum of data set = 110 + x

<em><u>The mean is given by formula:</u></em>

Mean = \frac{\text{sum of all numbers}}{\text{total numbers in data set}}

Substituting the values we get,

18 = \frac{110+x}{7}\\\\126 = 110 + x\\\\x = 126 - 110\\\\x = 16

Thus the missing number is 16

Lina20 [59]

In this question, it is given that

Walter wants computer software that cost $129. He has $57 saved.

he saves a maximum of $15 a week, the following inequality can be used to find how many weeks it will take Walter to save enough money to buy the software.

15x+57 \geq  129

And we have to solve this inequality for x.

First we subtract 57 to both sides. And on doing so , we will get

15x\geq  72

Dividing both sides by 15.

x \geq   4.8\

Correct option is A.
