Answer:

If I read this right

3 (n -12) + 14 = 4 (7 - 5n)

First, remove the parentheses

3 n - 36 + 14 = 28 - 20 n

Combining terms

23 n = 28 - 14 + 36 = 50

n = 50 / 23 = 2 4/23 = 2.17

Step-by-step explanation:

n= 60/23

3(n-12)+4=4(7-5n)

3n-36+4=4(7-5n)

3n-32=4(-5n+7)

+32 on both sides

3n=-20n+28+32

3n=-20n+60

Kim finds a 1-meter tree branch and marks it off in thirds and fifths. She then breaks the branch along all the markings and rem
True [87]

Answer:

3/5

Step-by-step explanation:

We want to find the fraction of the original branch that remains, so we will assume a length of the branch in order to make our calculation easier.

Since Kim marks it off in thirds and fifths, let's find the least common multiple of 3 & 5.

Least common multiple of 3 & 5 is 15.

Thus,let's make the length of the branch to be 15-meter long.

Now, if the branch is 15 m long, considering the markings of thirds and fifths, the branch would be cut at:

3, 5, 6, 9, 10, 12 meters.

We are told that She then breaks the branch along all the markings and removes one piece of every distinct length. Thus;

Distinct lengths are;

3 metres

5 - 3 = 2 metres

10 - 9 = 1 meter

Total she removes = 3 + 2 + 1 = 6 meters.

Total remaining is;

15 - 6 = 9 meters

Expressing this as a fraction of the original branch gives:

9/15

Divide both numerator and denominator by 3 to get; 3/5
