Answer:

x = 15

Step-by-step explanation:

y = family members = 7

x = cost of ticket

7x + 6y = 147

Substitute 7 for y:

7x + 6(7) = 147

7x + 42 = 147

Subtract 42 on both sides:

7x + 42 = 147

     - 42    -42

7x = 105

Divide both sides by 7:

7x = 105

x = 15

Answer 1-6 (about square root)
Taya2010 [7]

Answer:

1. For a cube, volume = edge^{3}

2. \sqrt[3]{volume} = edge

3. Volume of the cube = 216 so, the edge = \sqrt[3]{216} = 6

4. 1st blank = 6

   2nd blank = 6

   3rd blank = 216

   4th blank = 216

5. 6 is the edge

6. As the room is a square and we have to find the side

Area = 121

Edge = \sqrt[2]{121} = 11

If my answer helped, kindly mark me as the brainliest!!

Thank You!!
