The answer is -1. Hope this helps :)
You will divide the 12 by 28: 12/28 and that equals 3/7
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
Answer:
x = - 
Step-by-step explanation:
(x - 3) - 5 =
(x - 1)
Multiply through by 8 to clear the fractions
6(x - 3) - 40 = x - 1 ← distribute parenthesis and simplify left side
6x - 18 - 40 = x - 1
6x - 58 = x - 1 ( subtract x from both sides )
5x - 58 = - 1 ( add 58 to both sides )
5x = - 57 ( divide both sides by 5 )
x = -
