Tickets to a play cost $5 at the door and $4 in advance. The theater club wants to raise at least $400 from the play. Write and
cestrela7 [59]
Your equation should be
$4(40 tickets) + $5(X) = $400
160 +5x = 400
-160            -160
   0     5x =  340
  divide both sides by 5
5x/5 = 340/5
x = 68

so they need to sell 68 tickets at the door.

4(40) + 5(68) = 400
160 + 340  + 400
400 + 400

Find the value of x.
DiKsa [7]

Answer:

x = 135 degrees hopes this helps

Step-by-step explanation:

the whole triangle is equal to 180

180-41=139-94=45

so the missing angle in the triangle is 45

and that means the angle on the outside and the angle we just found 45 equals to 180

180-45=135

so 135 is the outside's missing angle
