Answer:
There are 8 dimes there.
Step-by-step explanation:
This question is solved used a system of equations.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
19 coins
This means that x + y = 19.
A nickel is worth $0.05. A dime is worth $0.1. The total of these coins is $1.35. So
0.05x + 0.1y = 1.35
How many dimes are there?
We have to find y.
From the first equation: x = 19 - y.
Replacing in the second:
0.05(19 - y) + 0.1y = 1.35
0.95 - 0.05y + 0.1y = 1.35
0.05y = 0.4
y = 0.4/0.05
y = 8
There are 8 dimes there.

Answer:
About 17 weeks
Step-by-step explanation:
Given
Ryan:
<em />
<em> (weekly)</em>
Sarah:
(weekly)
Required
Determine the number of weeks they have the same cards
Represent the number of weeks with w:
For Both individuals, number of card at any given week is:
So,
For Ryan, the expression is:
For Sarah, the expression is:
To determine the number of weeks, we have to equate both equations:
Collect Like Terms
Solve for w
16.6 implies about 17 weeks, because 16.6 approximates to 17
<em>Conclusively, Ryan and Sarah will have the same number of balls in about 17 weeks</em>
Hello there!
2(x + 5) = 3x + 1
You want to start with the distribution property
(2)(x) + (2)(5) = 3x + 1
2x + 10 = 3x + 1
2x - 3x = 1 - 10
-x = -9
Multiply by -1 to remove the negative sign
x = 9
3y - 4 = 6 - 2y
3y + 2y = 6 + 4
5y = 10
y = 10/5
As always, it is my pleasure to help student like you.
