22 = 5(y – 8) please help me

y=12.4

Step-by-step explanation:

22/5 is 4.4

so the numbers in the bracket must equal to 4.4

so y is 12.4

62/5 or 12 2/5

Step-by-step explanation:

22 = 5(y-8)

22 = 5y - 40

5y−40=22

Add 40 to both sides

5y−40+40=22+40

5y = 22+40

5y=62

Isolate the variable.

5y/5 = 62/5

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)
