Each gallon cost $6.23.
Explanation:
25-6.31=18.69
He spent $18.69 at the store since he has $6.31 left out of the $25 he originally had
He brought 3 gallons with an equal price each gallon so
18.69/3=6.23
He spent $6.23 on each gallon
Answer:
you mean trigonometry i'm assuming
but essentially:
soh = sin theta (the angle) = opposite length/hypotenuse length
cah = cos theta (angle) = adjacent length/hypotenuse length
toa = tan theta (angle) = opposite length/adjacent length
Step-by-step explanation:
The simplified expression is 6+3i
73 minus 24 plus 19 gives you 68 people left on the train.
