Answer:
Step-by-step explanation:
All the angels of a triangle always add up to 180
(2x-15)+(x+43)+x = 180
Multiple the numbers inside the parentheses first
-30x+43x+x = 180
Add common terms
14x = 180
Divide by 14 to get the variable by itself
x ≈ 12.86
Answer:
the answer to the equation is x + 12
Step-by-step explanation:
x + 5 + 7 = x + 12
x + 12
Answer:
48 people
Step-by-step explanation:
First, find how many were left after the first stop:
120(0.5)
= 60
Find how many were left after the second stop:
60(0.8)
= 48
So, since the rest got off on the third stop, this means 48 people got off on the third stop.
