Answer:
2 triangle surfaces: 2.5 X 2 X 1.7 = 8.5 square meters
9 X 2 = 18 square meters
18 X 3 = 54 square meters
54 + 8.5 = 62.5 square meters
Let "L" be Lila, "B" be Bob, and "C" be Carol.
L = B - 15
B = 35
L = 35-15 = 20
C = L/2
C = 20/2 = 10
Carol scores 10 points
6 wore blue + 5 wore green + 3 wore black = 14
If there are a total of 18 total students, then the number of people who wore other colored shirts is 4 because 18-14= 4. Therefore, 4/14, which is 2/7 simplified, represents the students who did not wear blue, green or black.

Answer:
let the scone be x and the large coffees be y.
7x+4y=$25.76-----equ(I)
2x+5y=$14.92-----equ(2)
make x the subject of the formulae in equation(ii).
x=$14.92/2-5y
x=7.46-5y
