-2(x + 1) = –2x+5
I don’t know have to do this. And I really need the answers

-2(x + 1) = -2x + 5  | distribute -2 into the parenthesis by multiplying

-2x - 2 = -2x + 5 | add 2x to both sides of the equation

-2 = 5 | final answer

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
