For this case we have the following system of equations:
-4x + 5y = 8
6x - y = 11
The solution is the ordered pair where both functions intersect.
In this case, the point of intersection is:
(x, y) = (5/2, 7/2)
Answer: (x, y) = (5/2, 7/2) option 1See attached image
1)5/24
2)1 and 1/3 im not sure
3)1 and 1/3
4)1/7
180cm. The square is 6 x 6 = 36 and the triangles = 12 x 6 = 72 and then divide it by 2 = 36 multiply that by 5 and you get 180cm
2 adults = 5.50 x 2 = 11
3 students = 4.25 x 3 = 12.75
Total = $23.75
8.9 x 10^-5 in scientific notation
