Question 96584: Isabella claims that the solution to 0.1x+10.5=10.55 is between 0 and 1. Is she correct?
a) Isabella is correct, because she knows that 0.1x must equal 0.50. Therefore, she must multiply 0.1 by a value between 0 and 1.
b) Isabella is correct, because she knows that 0.1x must equal 0.05. Therefore, she must multiply 0.1 by a value between 0 and 1.
c) Isabella is incorrect, because 01 multiplied by 0 equals 0 and 0.1 multiplied by 1 equals 0.1
d) Isabella is incorrect because the answer must be greater than 1 for the result of the equation to equal 10.55
Please help me... thank you

0.1x+10.5=10.55
subtract 10.5 from both sides.
.1x=.05
divide both sides by .1
x=.5, so the awnser must be a.
