D 32 miles to the gallon
976 divided by 30.5 equals 32
First let's make both the miles and the hours ran improper fractions:

So, to find our miles per hour, we have to divide the miles by the hours to get: 
Answer:
12a + 18 = 12a + 18
Step-by-step explanation:
times what's in the brackets by what's to the left of the brackets
Answer:
PA = XA
Step-by-step explanation:
Construction of an angle bisector,
1). Mark an arc from point W with the help of a compass which intersect lines WS and WZ at the points P and X respectively.
2). Marc two arcs of the same length form the points P and X which intersect each other at a point A.
3). Joint the points A and W.
Thus AW will be the angle bisector of angle PWX where PA = XA.
Therefore, distances PA and XA will be equal in measure.
