A bag contains 21 coins consisting of nickles and dimes. The total value of the coins is $1.70.
Write a system of equations that models this situation. How many nickels are in the bag?
Answers
Answer:
8
Step-by-step explanation:
x = nickles
y = dimes
0.05x + 0.10y = 1.70
x + y = 21
y = 21 - x
0.05x + 0.10 (21 - x) = 1.70
0.05x - 0.10x + 2.10 = 1.70
-0.05x + 2.10 = 1.70
-0.05x = -0.40
x = 8

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
If Hunter practices five days a week and a minimum of 450 minutes per week, then the total practice time for the week is at least 5 * 450 = 2250 minutes.
To find the average practice time per day, we can divide the total practice time for the week by the number of days:
The average practice time per day = total practice time for the week / number of days
The average practice time per day = 2250 / 5 = 450 minutes
Hence , on average, each basketball practice is 450 minutes/5 = 90 minutes

What is the distance between (2, 5) and (2,-5) on the coordinate plane
Answers
Answer:
10
Step-by-step explanation:
When you find the distance, you just add both of the numbers as if they were in absolute value 5+|-5|
so then since the x values are the same, you would go up/down 10 spaces on the Y-axis
Answer:
10 units
Step-by-step explanation:
Use the distance formula:
[tex]\sqrt{ (x_{2} - x_{1} )^2 -(y_{2} - y_{1} )^2[/tex]
Plug in values:
[tex]\sqrt{ (-5-5 )^2 -(2-2 )^2[/tex]

Some number subtracted by -6 is 41. Multiply this number by-3. Then divide
this number by -4. What is the final number?
Answers
Answer:
The final number is 26.25.
Step-by-step explanation:
First, solve the beginning sentence.
"Some number" can be represented by x
x - (-6) = 41
x + 6 = 41
x = 35
Next, solve the second sentence
35*(-3) = -105
Finally, the last sentence
(-105)/(-4) = 26.25
