What does n/5 - 3n/10 =1/5

Mathematics
1 answer:
dsp733 years ago
8 0
I assume you're looking for n.
so, take 2n/10-3n/10=2/10. Making everything have the same denominator is always easier.

This way, you have -n/10=2/10.

n=-2.

Kevin and Randy Muise have a jar containing 80 ​coins, all of which are either quarters or nickels. The total value of the coins
SCORPION-xisa [38]

Answer:

  • 39 quarters and 41 nickels

Step-by-step explanation:

Let the number of quarters be x and nickels be y.

<u>Given:</u>

  • Quarter is 25 cents
  • Nickel is 5 cents
  • Number of coins is 80
  • Total amount is $11.80 = 1180 cents

<u>We have equations:</u>

  • x + y = 80
  • 25x + 5y = 1180

<u>Solve the system by elimination, subtract 5 times the first equation from the second one:</u>

  • 25x + 5y - 5x - 5y = 1180 - 80*5
  • 20x = 780
  • x = 780/20
  • x = 39

<u>Find the value of y:</u>

  • 39 + y = 80
  • y = 80 - 39y = 41

<u>Verify:</u>

  • 25*39 + 5*41 = 975 + 205 = 1180

What is -7n-4=24 lol i hate homework
Montano1993 [528]
It's a simple linear equation in 'n'.  There's only one number that 'n' can be
that will make the equation a true statement.  That number is called the
'solution' to the equation.  Here's one way to find it:

You said that                       <u> -7n - 4  =  24</u>

Add  4  to each side:           -7n       =  28

Multiply each side by  -1 :    7n       =  -28

Divide each side by  7 :         <em>n        =  -4</em>

Homework is the only way for most people to learn stuff.
