♡ The Explanation/Step-By-Step ♡
- -4(-3n - 8) = 104
Divide both sides by -4!
-4(-3n - 8) over -4 = 104/-4
Simplify!
-3n - 8 = -26
Add 8 to both sides!
-3n - 8 + 8 = -26 + 8
Simplify!
-3n = -18
Divide both sides by -3!
-3n/-3 = -18/-3
Simplify!
n = 6

Answer:
none
Step-by-step explanation:
4 over 12 times 8 over 20
= 4/12 * 8/20 ....( 4/12 = 1/3; 8/20 = 2/5)
=1/3 * 2/5
=2/15
Answer:
5x -12 = 3x +8 (set the two = each other because they are the same length)
2x- 12= 8 (subtract 3x from both sides)
2x = 20 (add 12 to both sides)
x=10 (what x= for both expressions)
5(10) -12 (plug it into the first one to see what the length is and to see they're =
50 - 12 ( I already multiplied, now subtract)
38 (what the length of TR is)
3(10) +8 (plug it in again but into the other expression)
30+8 (multiply and add)
38 (the two have the same answer, so the x-value is correct.)
38+38= 76 (add the lengths of RS and TR and you get the length of TS)
