Given that 24 hours is one full day, we can deduce that 2400 hours is 100 days. One full cycle from that time is equivalent to that time therefore, 2400 hours after 5pm is 5pm.
So
Jon's age=j
mary age=m
m+j=27
m+2 times j=40
m+2j=40
M+j=27
ssubtract j from both sides
m=27-j
subsitute 27-j for m
27-j+2j=40
27+j=40
subtract 27 fromboth sdies
j=13
subsitue
13+m=27
subtract 13
m=14
mary=14
john=13
Answer:
13 sides
Step-by-step explanation:
1980 = (n − 2)×180 Formula for number of sides
n − 2 = 1980/180 Divide both sides by 180
n - 2 = 11
+ 2 + 2 Add 2 to both sides
n = 13
This what you gotta do 1+1=2 you get it
