Answer:
X = 5
Step-by-step explanation:
I think there a problem with the question, If there is one less person in the group then the payment by each remaining person is must more than $2 than the previous, because the rent cost unchanged but the number of people in the group decreased.
Before, cost per person :
After cost per person: =
However, the payment by each remaining person is more than $2 than the previous, so
=
+ 2
<=>
- 2x -40 = 0
<=> X = 5
2x + x = 15
I'm not sure if that's what your asking but that's the equation used to find x.

Answer:
Linear expression
Step-by-step explanation:
If you have an expression with = sign, it becomes an equation
Without the = sign, it's just an expression
Answer:
taking z as the reference angle XY becomes perpendicular and YX becomes base thus SIN Z= P/H
SIN Z = 30/50
therefore sin z= 0.6
