Answer:
54
Step-by-step explanation:
First, subtract the kids in the cars. These kids aren't on buses.
228 - 12 = 216 kids on buses
Next, divide the 216 kids into 4 buses.
216 / 4 = 54
There were 54 kids on each bus.
Answer:
-2
Step-by-step explanation:
4x+4=-3x-10
7x=-14
x=-2
Answer:
x = 78
Step-by-step explanation:
We can find angle y
D + B + y = 180 since the sum of the angles of a triangle are 180
31+47+ y =180
78+y = 180
y = 180 - 78
y = 102
x+y = 180 since they form a straight line
x + 102 = 180
x = 180-102
x = 78
