Solve for n: -6(n -8) = 4(12 -5n) + 14n.​

Answers

Answer 1
Answer:

Answer:

infinite solutions

Step-by-step explanation:

Given

- 6(n - 8) = 4(12 - 5n) + 14n ← distribute parenthesis on both sides

- 6n + 48 = 48 - 20n + 14n, that is

- 6n + 48 = 48 - 6n ( add 6n to both sides )

48 = 48 ← True

This indicates that the equation is true for any value of n
Answer 2
Answer:

Answer:

This is a very classical type of equation in which, the solution is basically any number and it is known as an "Identity". So it has infinite solutions

Step-by-step explanation:

  • Apply the distributive law to both sides of the equation:

-6(n-8) = 4(12-5n)+14n

-6n-6*(-8) = 4*12+4*(-5n) + 14n

  • Reduce similar terms

-6n+48=48-20n+14n

-6n+48=48-6n

  • From here it is clear them to see that by adding -48 and 6n to both sides one obtains the identity 0 = 0

-6n+48=48-6n

-6n +6n + 48 -48 = 48 -48 - 6n + 6n

0 = 0

  • So every time you find this kind of problem and after reducen the equation you end up with a true statement, then the equation has infinite solutions

Dylan is rollerblading along an 8 mile trail in the forest park she stopped for water after 2.4 miles. After another 3.1 miles, she stopped for lunch. ABOUT (round) how much farther does she have to go to reach the end of the trail? SHOW YOUR WORK!

Answers

Add up the amount of miles she actually reached to

2.4 + 3.1 =

5.5 = miles already traveled

And then subtract it from the 8 mile trail

8 - 5.5 =

2.5 miles

About 2.5 or 3 miles (rounded to the tenth or whole number?)
