Find the value of x that makes A||B

x = 10

Step-by-step explanation:

(4x)° & (3x+10)° are corresponding angles. If both the angles will be equal , then we can say that A║B.

If the value of x will be 10 , then it will make A║B.

2 x t divided by n

step-by-step explanation:

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)
