Answer:

Step-by-step explanation:
3/8 + 1/4 + 1/2 - 2/3
- > 1/4 = 2/8
3/8 + 2/8 + 1/2 - 2/3
5/8 + 1/2 - 2/3
- > 1/2 = 4/8
5/8 + 4/8 - 2/3
9/8 - 2/3
- > LCM of 8,3: 24
- > 9/8 = 27/24
- > 2/3 = 16/24
27/24 - 16/24
11/24

-6 ÷ 4x = 15, six is less than the quotient and quotient mean division, replace a number with a variable and put it with four and the you would put equal 15
Five goes into 11, two times. So each friend gets two cookies and 1/5 of the last one. So the answer is 2 and
1/5
5n + 34 = -2(1 - 7n)
5n + 34 = -2 + 14n
5n = -36 + 14n
-9n = -36
9n = 36
n = 4
