Answer:
- 39 quarters and 41 nickels
Step-by-step explanation:
Let the number of quarters be x and nickels be y.
<u>Given:</u>
- Quarter is 25 cents
- Nickel is 5 cents
- Number of coins is 80
- Total amount is $11.80 = 1180 cents
<u>We have equations:</u>
- x + y = 80
- 25x + 5y = 1180
<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>
- 25x + 5y - 5x - 5y = 1180 - 80*5
- 20x = 780
- x = 780/20
- x = 39
<u>Find the value of y:</u>
- 39 + y = 80
- y = 80 - 39y = 41
<u>Verify:</u>
- 25*39 + 5*41 = 975 + 205 = 1180
Yes, 0.069 is less than 0.07~
First, we compare the "one" place: 0 = 0.
Second, we compare the "tenth" place: 0 = 0.
Next, we compare the "hundredth" place: 6 < 7.
Because 6 < 7, 0.069 < 0.07 as a result~
I don’t bro cuz I need help to
The set of integers consists (0), the positive natural numbers (1,2,3,) also called whole numbers, and their additive inverses the negative integers(-1, -2, -3,).
