I need help with #2
andrew-mc [135]

Answer:

28 < x < 114

Step-by-step explanation:

  • x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.
  • But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well
  • 43 + x > 71            Subtract 43 from both sides.
  • 43-43 + x > 71 - 43
  • x > 28
  • To put this in the form of the answer you need it looks like this.
  • 28 < x < 114

A bag contains green marbles and blue marbles,
dexar [7]

There are 13 green marbles in the bag.

Step-by-step explanation:

Total marbles = 18

Let,

Green marbles = x

Blue marbles = y

According to given statement;

The number of green marbles is 2 less  than 3 times the number of blue marbles.

x = 3y-2    Eqn 1

x+y=18      Eqn 2

Putting value of x from Eqn 1 in Eqn 2;

(3y-2)+y=18\\3y-2+y=18\\4y=18+2\\4y=20

Dividing both sides by 4

\frac{4y}{4}=\frac{20}{4}\\y=5

Putting y=5 in Eqn 1

x=3(5)-2\\x=15-2\\x=13

There are 13 green marbles in the bag.
