Answer:
11 because 10x2=20 and the 220 divided by 20 =11
Step-by-step explanation:
So he started at
9:30 a.m.
three hours and ten minutes later
9+3 is 12
30 + 10 is 40
12:40 p.m.
it took him 47 minutes to replace
so 12:40 plus 47 minutes is
1:27 p.m.
He then rode for another 56 minutes to finish the race
so 1:27 plus 56 minutes
2:23 p.m.
Hope this helps :)
There are 25 $10 bills and 11 $20 bills.
Step-by-step explanation:
Given,
Worth of proceeds from garage = $470
Let,
x be the number of $10 bills
y be the number of $20 bills.
According to given situation;
10x+20y=470 Eqn 1
x = y+14 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 30
Putting y=11 in Eqn 2
There are 25 $10 bills and 11 $20 bills.
