Answer:
Step-by-step explanation:
sum of all the angles in a triangle=180
let the angles be 2x, 4x and 3x
so, 2x+4x+3x=180
9x=180
x=20
so smallest angle 2x= 2(20)= 40 degrees
135 because 10+5= 15. 15(9)=135. 6-5=1. so 135/1=135
Answer:
0.45=9/20
27/50=0.54
4/5=80
17/25=0.68
38%=19/50

Answer:
(C) 220
Step-by-step explanation:
Let x represent the number of adult tickets sold and y represent the number of student tickets sold. With the information given, we can set up two equations:
(Since for every adult ticket sold, $5 is made and for every student ticket sold, $3 is made)
In the first equation, we can represent x in terms of y:

And then, we can substitute x in the second equation for 360 - y to get:
which simplifies to:
and therefore,
.
