In one baseball season, Nolan hit twice the difference of the number of home runs Mrs. Davis hit and 6. Altogether, they hit 18

Alborosie

Answer:

Nolan hitted 8 home runs

Step-by-step explanation:

Let's call the number of home runs that Nolan hitted by N, and that Davis hitted by D.

So, we can write the following equations:

N = 2 * (D - 6)

N + D = 18

Now we can solve the system of equations, using the value of N from the first equation in the second one:

2 * (D - 6) + D = 18

2*D - 12 + D = 18

3*D = 30

D = 10

Now we find N:

N + D = 18

N + 10 = 18

N = 8

So we have that Nolan hitted 8 home runs.

Katyanochek1 [597]

Answer: 33 students wore blue jeans .

Step-by-step explanation:

Let x be the number of black pants.

Given : For the choir concert, the choir director has asked that everyone wear either black pants or blue jeans.

Three times as many students wore black pants as blue jeans.

i.e. Number of blue pants = 4x

If there are forty-four students in the choir, then we have

$x+3x=44\\\\\Rightarrow\ 4x=44$

Divide both sides by 4 , we get

$x=11$

Thus , the number of black pants = 11

Then , the number of blue pants = $3\times11=33$

Therefore, 33 students wore blue jeans .

y = x2 - 6x - 8 Complete the square in the quadratic equation in order to write the equation in vertex form.

Airida [17]

Answer:

y = (x-3)^2 - 17

Step-by-step explanation:

To complete the square, take the middle term bx and divide it in two. Then take the square.

x^2 - 6x - 8 has bx = -6x. Take -6/2 = -3. Square -3^2 = 9.

Now to finish completing the square add 9 and subtract 9 from one side.

y = x^2 - 6x - 8

y = (x^2 - 6x +9) -9 - 8

y = (x-3)^2 - 17
