Answer:

14x+7 = 30

Step-by-step explanation:

7y +6 = 36

y = 2x+1

Substitute the second equation into the first for y

7(2x+1) +6 =36

Distribute

14x+7 +6 = 36

14x+13 =36

Subtract 6 from each side

14x+13 -6 = 36-6

14x+7 = 30

Answer:

Step-by-step explanation:

7y + 6 = 36

7(2x + 1) + 6 = 36

14x + 7 + 6 = 36

14x + 13 = 36

14x + 13 - 6 = 36 - 6

14x + 7 = 30

igor_vitrenko [27]

Answer:

0.4625 or 46.25%

Step-by-step explanation:

The data for the percentage of contribution and the percentage of numbers from each suburb is presented in the table bellow:

$\begin{array}{ccc}&Contribution (C)&Number(N)\\Belle\ Mead&0.60&0.25\\Oak\ Hill&0.55&0.25\\Antioch&0.35&0.5\end{array}$

The probability that she gets a donation is given by the sum of the probabilities of getting a donation from each suburb weighed by their respective percentage of numbers of the list:

$P(C) = P(C_B)+P(C_O)+P(C_A)\\P(C) =0.6*0.25+0.55*0.25+0.35*0.5\\P(C) = 0.4625$

The probability that she gets a donation is 0.4625 or 46.25%.
