Answer:
She takes 18 to school.
1/5 of 30 is 6 so 2/5 of 30 is 12
30 minus 12 is 18
u( t - 2s)
double s is expressed as 2s
subtract this result from t gives t - 2s
multiply this result by u gives u × (t - 2s) = u( t - 2s)
B=12.2
C=5.4 is your answer
n = 28 degree
Step-by-step explanation:
2n + 17 + 2n - 5 + 2n = 180 degree (sum of interior angles of a triangle)
6n +12 = 180
6n = 180 - 12
n = 168/6
