First find least common denominator to subtract.
9=(3)×3
15=(3)×5
3×3×5=45 is lcd
4/9=20/45
7/15=21/45
(20/45-21/45)=(20-21)/45=-1/45
-1/45÷13/10
multiply by reciprocal instead of dividing
-1/45×10/13=(1×10)/(45×13)
-10/585
Answer:
8 am Monday
Step-by-step explanation:
The difference between the two watches is 2+1= 3 minutes.
It would take 60/3 = 20 hours to have a difference of 60 minutes.
From noon Sunday it would be more 20 hours the earliest time there would be a difference of one hour between the two watches' time.
12 noon + 20 hours= 8 am Monday
Answer:
DC = 2
Step-by-step explanation:
The wrong equation was used.
The right equation to use based on the midsegment theorem of a trapezoid is:
MN = ½(AB + DC)
MN = 8
AB = 14
Substitute
8 = ½(14 + DC)
Multiply both sides by 2
8*2 = ½(14 + DC)*2
2*8 = 14 + DC
16 = 14 + DC
16 - 14 = 14 + DC - 14
2 = DC
DC = 2
