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.

Answer:
b is the answer
Step-by-step explanation:
We're going to start with the first one
60m/1 HR
The ratio is already in lowest terms so we found an equivalent ratio by multiplying both terms by 2. So it would be 120 : 2
The next one only has 1 number and that is 1
It is not a form of a ratio because you can't turn a one digit number into a ratio. A ratio has two digits for each side for an example:
This can be turned into a ratio / 19 to 8
This cannot be turned into a ratio/ 8
So there you have it letter b is your answer.
60 inches.
Because you will do 5x12= 60
You get 12 from the inches in a foot!
Hope this help!!
