Answer:

B

Step-by-step explanation:

y = - x + 10 → (1)

y = 7x + 2 → (2)

Substitute y = 7x + 2 into (1)

7x + 2 = - x + 10 ( add x to both sides )

8x + 2 = 10 ( subtract 2 from both sides )

8x = 8 ( divide both sides by 8 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 7(1) + 2 = 7 + 2 = 9

solution is (1, 9 ) → B

Variable g is 5 more than variable w. Variable g is also 2 less than w. Which pair of equations best models the relationship bet
jeyben [28]
Your answer is the first choice, g = w + 5    &    g = w − 2, because if variable g is 5 MORE THAN variable w, that would mean you would have to add 5 to w in order to get g, (g = w + 5), but if it said it was 5 TIMES MORE THAN, THHHHEEEENNNNN that would mean w times 5.
Now da second problem is g = w - 2, because they said that g is 2 LESS THAN w, so you would have to subtract 2 from w to get g, also known as g = w - 2.

23+8-(14-(7-2+3) step by step
Snowcat [4.5K]

Step 1: Do the most inner parenthesis (7-2+3) = 5 + 3 = 8.

23+8-(14-8)

Step 2: Do the next parenthesis (14-8) = 6

23+8-6

23+8 = 31

31 - 6 = 25

So, 25 is your answer!

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
