<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>
Kilograms is a type of measurement for weight, and so the converted measure should also be weight (which leaves only oz. and lbs.)
The converting ratio of kilograms to pounds is: 1 = 2.2
The converting ratio of kilograms to ounces is: 1 = 35.274
This means that pounds, or (B) is your closest answer
hope this helps
Y=20x+120
y=30x
30x=20x+120
30x-20x=120
10x=120
x=12 days
y=30x
y=30(12)
y=360 minutes
Answer:
Step-by-step explanation:
9/15y + 3/21 = 5/15 y - 14/21. Adding 14/21 to both sides we then get 9/15y + 17/21 = 5/15y. Subtracting 5/15y from both sides, we get 4/15y + 17/21 = 0.
Then we get 4/15y = -17/21. Dividing by 4/15 gets us -17/21 * 4/15 = -68/315 = y.
