Answer:
(12 nickels))
(5 dimes)
Step-by-step explanation:
Based on the information given in the problem, you can set up the following system of linear equations, where:
x: number of nickels.
y: number of dimes.
Then
FIRST EQUATION: 
SECOND EQUATION: 
(in cents)
You can apply the Substitution method:
- Solve for x from the first equation.
- Substitute into the second equation and solve for y.
Then:
- Find x:
Answer:
1 min : 12 min
Step-by-step explanation:
To simplify the given ratio, convert both to the same unit of time.
1 hour = 60 minutes
3 hours = 3 x 60 minutes
= 180 minutes
So that,
15 min : 3 hours = 15 min : 180 min
divide through by 15 to have;
15 min : 180 min = 1 min : 12 min
Thus the simplified form of the number give is 1 min : 12 min.
Well you can simplify them by dividing by there greatest common factor.
In this case they can both divide by 12!
Thats the biggest number they can divide by...
Soo..
36 ÷ 12 = 3
----------------
48 ÷ 12 = 4
So your answer is 3/4!
Good Luck! :)
Answer:
x = 15, y = 4
Step-by-step explanation:
By Basic proportionality theorem, we have:
x/ 5 = 18/6
x = (18*5)/6
x = 90/6
x = 15
Again By Basic proportionality theorem, we have:
12/y = 18/6
y = (12*6)/18
y = 72/18
y = 4
It's the bottom one. 20 dollars has to be less than or equal to the amount. you cannot spend more than $20
