You and a friend go to the movies and split the cost of the movie tickets and snacks. You pay the bill. You tell your friend he
Nastasia [14]

Ok so you divide the bill by 2 because you each are paying half. You knock off $4 because you owed him that from last time and you pay $9. So this would equal to b/2 -4 =9. If you work it out in reverse, you get 4+9 which equals 13 then multiplied by 2 which means the total bill was $26.

So we have 5+3x=11. We subtract 5 from both sides and get 3x=6. we divide both sides by 3 and get x=2. Daniella skated for 2 hours

In parallelogram EFGH, EJ = 6x + 3 and JG = 10x - 5 What is EG?<br>A: 15<br>B: 12<br>C: 25<br>D: 30​
Ne4ueva [31]

Answer:

  • D. 30

Step-by-step explanation:

It seems J is the intersection of diagonals.

We know diagonals of the parallelogram bisect each other.

<u>It gives us:</u>

  • EG = EJ + JG and
  • EJ  = JG

<u>Substitute and solve for x:</u>

  • 6x + 3 = 10x - 5
  • 10x - 6x = 3 + 5
  • 4x = 8
  • x = 2

<u>Find the value of EJ:</u>

  • EJ = 6*2 + 3 = 15

<u>Find the value of EG:</u>

  • EG = 2*EJ = 2*15 = 30

Correct choice is D
