3/4*3=?
3/4*3/1=9/4
9/4=2 1/4
Answer:
B
Step-by-step explanation:
Why? Because of you find the unit rate of b it will be bigger and if you find the unit rate of a it will be smaller :)
Answer:
<DEF = 107
Step-by-step explanation:
The way to best solve this problem is by starting with angle F. Remember that all angles in a straight line must add up to 180. So by subtracting 135 from 180 we get 45 for angle F.
180 - 135 = 45
After that, we can figure out the measure of <DEF. All the angles of a triangle must add up to 180. So:
180 - 28 - 45 = 107
Making the answer 107 for the measure of <DEF
9C5 = 9!/[5!(9-5)!
9C5 = 9!/(5!)(4!)
You finish.
7P4 = 7!/(7-4)!
7P4 = 7!/3!
You finish.
