Answer:
6 7/8 miles per hour
Step-by-step explanation:
2 3/4 ÷ 2/5
change mixed number into improper fraction; 2 3/4 = 11/4
when dividing fractions, multiply by the reciprocal of the second fraction
11/4 ÷ 2/5 = 11/4 · 5/2 = 55/8 or 6 7/8 mph
What is x in this situation?
The measure of angles are 69 degree and 111 degree
<em><u>Solution:</u></em>
Given is linear pair angles
The measure of angles are: (6x - 9) degrees and (9x - 6) degrees
A linear pair of angles is formed when two lines intersect.
The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Therefore,

<em><u>Thus the measure of angles are:</u></em>

Thus measure of angles are 69 degree and 111 degree
4=c
5= a
