Which one the highlight one
Answer:
Step-by-step explanation:
Let one angle = A
Let the other angle = B
A + B = 180
A = B - 16.4 Substitute for A in the top equation
B - 16.4 + B = 180 Combine the left
2B - 16.4 = 180 Add 16.4 to both sides
2B = 180 + 16.4
2B = 196.4 Divide by 2
B = 196.4/2
B = 98.2
A = B - 16.4
A = 98.2 - 16.4
A = 81.8
Step-by-step explanation:
2x - 3y = 25
+ (5x + 3y = 10)
=> 7x = 35, x = 5.
Therefore 2(5) - 3y = 25, 3y = -15, y = -5.
The solution pair is (5,-5).
92 students were on the bus and half left
so thats 92/2 and you get 46
46 students were left on the bus
