If the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?
Olegator [25]

Answer:

b+6

Problem:

If the average of b and c is 8, and d=3b-4, what is the average of c and d in terms of b?

Step-by-step explanation:

We are given (b+c)/2=8 and d=3b-4.

We are asked to find (c+d)/2 in terms of variable, b.

We need to first solve (b+c)/2=8 for c.

Multiply both sides by 2: b+c=16.

Subtract b on both sides: c=16-b

Now let's plug in c=16-b and d=3b-4 into (c+d)/2:

([16-b]+[3b-4])/2

Combine like terms:

(12+2b)/2

Divide top and bottom by 2:

(6+1b)/1

Multiplicative identity property applied:

(6+b)/1

Anything divided by 1 is that anything:

(6+b)

6+b

b+6

Answer: r = 11

Step-by-step explanation:

We know that the point (-2, r) lies on the graph of:

2*x + y = 7.

Then, if we that point is on the graph of the equation, we can replace the values and we will have:

2*(-2) + r = 7

and now we solve this for r-

-4 + r = 7

r = 7 + 4 = 11

r = 11

Maria in on the school softball team. Her team has won 3 out of 12 games. She is having an excellent season hitting the softball
GarryVolchara [31]

Ignore the part about her batting attempts, it is extra. Her winning ratio is 3/12 which is 1/4 simplified and if you do 1/4 or 3/12 you get 0.25 which is the decimal of how many games she won / how many total. To convert 0.25 to percentage multiply it by 100 to get 25% D
