Question 64660: Thank you for your help
Solve for x to four decimal places
18. 10x = 153
19. 1.024x = 2

You can put this solution on YOUR website!
18. 10x = 153
10x/10=153/10 [isolate the x]
x=15.3
checking:
10(15.3)=153
153=153 [checks out]
.
19. 1.024x = 2 [isolate the x]
1.024x/1.025=2/1.024
x=1.953125
rounding off to four decimal places: x=1.9531
checking:
1.024(1.9531))=2
1.99992=2 [close enough]
