A tiny area on a computer chip measures 2.3x 10-3 mm by 1.7x 10-4 mm. About how many times longer is the longer dimension than the shorter dimension???
A)1.35
B)6
C)7.4
D)13.5

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
