Answer: the coin bank has 50 dimes and 16 quarters.
Step-by-step explanation:
The worth of a dime is 10 cents. Converting to dollars, it becomes
10/100 = $0.1
The worth of a quarter is 25 cents. Converting to dollars, it becomes
25/100 = $0.25
Let x represent the number of dimes in the coin bank.
Let y represent the number of quarters in the coin bank.
A coin bank containing only dimes and quarters has 34 more dimes than quarters. This means that
x = y + 34
The total value of the coins is $9. This means that
0.1x + 0.25y = 9 - - - - - - - - - - - 1
Substituting x = y + 34 into equation 1, it becomes
0.1(y + 34) + 0.25y = 9
0.1y + 3.4 + 0.25y = 9
0.1y + 0.25y = 9 - 3.4
0.35y = 5.6
y = 5.6/0.35 = 16
x = y + 34 = 16 + 34
x = 50
1 16/40 simplified, is 1 2/5.
10 3/5 is the anwser to the question
Hey there :)
To find the slope with <em>two points</em> we will need to use the equation
( 3 , -20 ) ( 5 , 8 )
Here is what the equation should look like when replaced with the numbers (<em>it will be a fraction</em>) :
We know that <em>two negatives</em> cancel out and make a positive, so the numerator would actually be 8 + 20.
Solve the fraction and we get
28 <em>divided</em> by 2 is 14. The slope is 14.
