Answer:
C
Step-by-step explanation:
The answer is BFG because those angles form a triangle while the other options form pyramids
8th grade = 3x = 3(47) = 141 band members.
7th + 8th = 188
7th = x
8th = 3x
x + 3x = 188 ; x = 47 ; 47 + 3(47) = 47 + 141 = 188
4x = 188
4x / 4 = 188 / 4
x = 47 --> 7th grade
8th grade = 3x = 3(47) = 141
To check:
x + 3x = 188 ; x = 47 ;
47 + 3(47) = 188
47 + 141 = 188
188 = 188
Remember that a percentage means "parts out of 100". 24% in decimal form is therefore 0.24, because it is 24 out of the possible 100, or 1.0. To find 24% of 75, you just multiply 0.24 times 75:
75 x 0.24 = 18
