Answer:15x
Step-by-step explanation:you add 12 + 3 which equals 15 and then you just carry the x over
Log x+ log 7= log 42
log x=log 42 - log 7
log x=log 42/7 [ log a - log b= log (a/b) ]
log x= log 6
therefore:
x=6
Answer: x=6
0.8%=6
6/8=0.75(0.1%)
0.75*1000=750(100%)
Answer=750
Proof= 750*0.008=6
