Question

Solve the old 2x+log12=3 round to the nearest hundredth if necessary

6,000
24,000
166.67
41.67

Answer 1

41.67

Explanation:

log 2x+log12=3

log (a) + log (b) = log (ab)

log (2x*12) =3

log (24x) = 3

raise each side to the power of 10

10 ^ log (24x) = 10 ^3

24x = 1000

divide by 24

24x/24 = 1000/24

x = 41.666666666......

rounding to the nearest hundredth

41.67
