Find x when 0.02x + 0.7 > 0.8 .
a. x > 0.5
b. x > 2
c. x > 5
d. x > 50

Answer 1

Any ideas on where to start?

Answer 2

well I tried but I'm not sure it is right... could it be C. x>5?

Answer 3

That's correct but do you know how to get the answer ?

Answer 4

0.02*5+0.7>0.8

Answer 5

You wouldn't multiply
0.02x + 0.7 > 0.8 .
start by subtracting 0.7 from both sides what do you get?
0.02x + 0.7-0.7 > 0.8-0.7

Answer 6

0.02x+0>0.1?

Answer 7

good and then you just divide both sides by 0.02

Answer 8

and you get x>5 (which you got as your answer)
I hope you understand a bit better now :-)
