A Major League Baseball stadium sells three types of tickets. Reserved tickets are sold for $20 each, field-level tickets are sold for $50 each, and box seat tickets are sold for $100 each. You purchase 10 total tickets for $370. You have twice as many reserved tickets as field-level tickets.

Answers

Answer:

There were 6 reserved tickets, 3 field level tickets and 1 box seat tickets

Step-by-step explanation:

Let x represent the number of reserved tickets, y represent the number of field level tickets and z represent the number of box seat tickets.

Given that 10 total tickets were bought for $370, hence this can be represented by the equation:

20x + 50y + 100z = 370          (1)

x + y + z = 10        (2)

Also there was twice as many reserved tickets as field-level tickets. This can be represented by the equation:

x = 2y

x - 2y = 0             (3)

solving equations 1, 2, and 3 simultaneously gives:

x = 6, y = 3 and z = 1

There were 6 reserved tickets, 3 field level tickets and 1 box seat tickets

-2|2x+4|+10>-6

Answers

Answer:

-6 < x < 2

Step-by-step explanation:

-2|2x+4|+10>-6

Subtract 10 from each side

-2|2x+4|+10-10>-6-10

-2|2x+4|>-16

Divide by -2, remembering to flip the inequality

-2/-2|2x+4|>-16/-2

|2x+4|<8

We have two solutions, one positive and one negative( remember to flip the inequality)

2x+4 < 8    and 2x+4 > -8

Subtract 4 from each side

2x+4-4 < 8-4    and 2x+4-4 > -8-4

2x < 4             and   2x > -12

Divide by 2

2x/2 < 4/2             and   2x/2 > -12/2

x <2                and           x > -6

-6 < x < 2

Answer:

x<2 and x>-6

Step-by-step explanation:

First, get rid of anything on the outside of the absolute value bars. Subtract the 10 on both sides first.

-2|2x+4|+10>-6

             -10  -10

-2|2x+4|>-16

Now, divide by -2 on both sides.

-2|2x+4|>-16

/-2           /-2

|2x+4|<8

Just so you know, any time you multiply or divide by a negative, flip the inequality sign. Now because the numbers in the absolute bars are by themselves, you can start to finally solve. But, when you have an equation with absolute bars and you have the numbers in the absolute bars by themselves, you always have to split it into two equations. The equations have to be identical, but the number on the opposite side of the x has to be negative. Now, you solve both equations just like regular ones. Also, flip the sign for the inequality with the negative number.

|2x+4|<8    and     |2x+4|>-8

     -4  -4                     -4  -4

2x<4                      2x>-12

/2  /2                      /2   /2

x<2          and          x>-6

I hope this helps you out!!! Have an amazing day C:

Answers

Answer:

It is an undefined line which means a vertical line.

Step-by-step explanation:

Using the point-slope formula y2-y1 divided by x2-x1, you would get -4-(-7)/-3-(-3) which the answer would be 3/0. If zero is at the bottom of the fraction, the line would be undefined.

Rhoda is correct because 0.9² is 0.81 is less than 0.89 but 1.0² is 1 which is still greater than 0.89.

Answers

Given:

Three equations are

[tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex]

[tex]4(0.5x-2)+3x=-14-(x+6)[/tex]

[tex]8(0.5x-3)+4x=-9-(x+6)[/tex]

Three solutions are [tex]x=-2,x=-1,x=1[/tex].

To find:

The solution of each equation from the given solutions.

Solution:

We have,

[tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex]

Using distributive property, we get

[tex]3x-9+2x=-9-x-6[/tex]

[tex]5x-9=-15-x[/tex]

Isolate variable terms.

[tex]5x+x=-15+9[/tex]

[tex]6x=-6[/tex]

Divide both sides by 6.

[tex]x=-1[/tex]

Similarly,

[tex]4(0.5x-2)+3x=-14-(x+6)[/tex]

[tex]2x-8+3x=-14-x-6[/tex]

[tex]5x-8=-20-x[/tex]

[tex]5x+x=-20+8[/tex]

[tex]6x=-12[/tex]

[tex]x=-2[/tex]

Now,

[tex]8(0.5x-3)+4x=-9-(x+6)[/tex]

[tex]4x-24+4x=-9-x-6[/tex]

[tex]8x-24=-15-x[/tex]

[tex]8x+x=-15+24[/tex]

[tex]9x=9[/tex]

[tex]x=1[/tex]

Therefore, the solutions of given equations [tex]6(0.5x-1.5)+2x=-9-(x+6)[/tex], [tex]4(0.5x-2)+3x=-14-(x+6)[/tex] and [tex]8(0.5x-3)+4x=-9-(x+6)[/tex] are x=-1, x=-2 and x=1 respectively.

Answer:

Step-by-step explanation:

[tex]\frac{k}{4} + 3 = 14[/tex]

Subtract 3 from both sides

Multiply both sides by 4 to find k.

1/2r + 2 (3/4r - 1) = 1/4r + 6

Answers

Answer:

r=32/7

Step-by-step explanation:

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

1/2r + 2 (3/4r - 1) = 1/4r + 6

Step 1: Simplify both sides of the equation.

1/2r + 2 (3/4r - 1) = 1/4r + 6

1/2r+(2)(3/4r)+(2)(-1)=1/4r+6(Distribute)

1/2r+3/2r+-2=1/4r+6

(1/2r+3/2r)+(-2)=1/4r+6(Combine Like Terms)

2r+-2=1/4r+6

2r-2=1/4r+6

Step 2: Subtract 1/4r from both sides.

2r-2-1/4r=14r+6-14r

7/4r-2=6

Step 3: Add 2 to both sides.

7/4r-2+2=6+2

7/4r=8

Step 4: Multiply both sides by 4/7.

(4/7)*(7/4r)=(4/7)*(8)

r=32/7

Answer: r=32/7
