Answer:
n = 7
Step-by-step explanation:
You will want to add all common factors with each other.
So that would be n + 3n + 5n which would be 9n.
Then -8 + 1 would be -7. So now it should be 9n - 7.
You are going to set 56 equal to 9n - 7, so that would be 9n - 7 = 56.
After that, you will have to leave 9n alone by itself, so you would have to add 7 to both sides. Your final equation should be 9n = 63.
After that, you should divide both sides by 9 since you want n alone.
So 63 ÷ 9 would be 7. So at the end, <u>n = 7.</u>
Answer: =2 2 /3
Step-by-step explanation: =32÷412÷4=83
Converting to a mixed number using long division with remainders for 8 ÷ 3.
8÷3=2R2
Therefore:
83=223

Answer:
m=-5
Step-by-step explanation:
Answer: 1/7
Explanation:
1. Use the formula, y2-y1/x2-x1
Plug in the points, (12, -8) and (-9, -11) into the formula.
Point (12, -8): 12 is the X1 and -8 is the y1.
Point (-9, -11): -9 is the X2 and -11 is the y2
So, -11--8/-9-12
2. -11--8/-9-12= -3/-21= 1/7
I hope this helps!!
