25 + 3.2+ .04
28.24
<span>Amanda has 26 nickels and dimes.
We shall call nickels x and dimes y.
We can write the following equations:
x = 3y -2 or -x +3y = 2
x + y = 26
We can cancel out the x to give 4y = 28 or y = 7
If there are 26 coins in total and 7 of them are dimes then there must be 19 nickels.
The number of nickels (19) is two fewer than three times the number of dimes ( 3(7) - 2 = 19).</span>
X= 44 and Y= 46 . PLEASE MARK BRANLIEST
Answer:
4 days
Step-by-step explanation:
In this question, we are asked to calculate the number of days Melvin commutes if she commutes at a certain rate per day and last week, she took 14hours to commute.
Now, this is a rate question. She commutes at a rate of 3.5hrs per day and she commuted a total of 14 hours.
To get the number of days for which she has commuted, we simply divide the number of hours of commuting by the rate at which she commutes per day.
Mathematically, this equals 14/3.5 = 4 days
1) 200 + 400 = 600
200/600 = 1/3
1/3 X 100 = 33%
200 = 33%
400 = 66 % (C)
2) 100/500 = 1/5
1/5 X 100 = 20% (C)
