Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have

2 x 4k - 2 x 3

which gives you

8k - 6

Answer:

Taniyah

Step-by-step explanation:

Taniyah is correct because you need to:

diistribute : 8k - 6 - 6k = 14

combine like terms : 2k - 6 = 14

add 6 to both sides : 2k - 6 + 6 = 14 + 6

simplify : 2k = 20

divide both sides by the same factor : 2k/2 = 20/2

simplify : k = 10

12) A new amusement park decides to offer its visitors a choice between two plans. With Plan 1 they pay $6 to enter
astraxan [27]

9514 1404 393

Answer:

  • 3 rides
  • $16.50

Step-by-step explanation:

The plan 1 cost for x rides will be ...

  y = 6 + 3.50x

The plan 2 cost for x rides will be ...

  y = 12 + 1.50x

These costs will be equal when ...

  y = y

  6 + 3.50x = 12 + 1.50x . . . . . substitute for y

  2.00x = 6 . . . . . . . . . . . . . subtract 6+1.50x

  x = 3 . . . . . . . . . . . . . . . divide by 2

For 3 rides, the cost will be the same.

__

For 3 rides the cost is ...

  y = 6 + 3.50(3) = 6 + 10.50 = 16.50

The cost for 3 rides will be $16.50 for either plan.

Write the integer that best represents 23 degrees below zero
padilas [110]
23 below zero means you will actually subtract (remove) 23 from zero.
This can be represented using the following expression: 
0 - 23

To represent this as an integer, this means you will use a negative sign to represent the removal or subtraction of the number followed by the number removed which is 23, therefore:
The integer to represent this is -23.

8t-r=12t , solve for t
WITCHER [35]
<span>8t-r=12t
Add r to both sides
8t=12t+r
Subtract 12t from both sides so that t can only be on one side
-4t=r
Divide both sides by -4
Final Answer: t= r/-4</span>
