I am a decimal

dybincka [34]

0.6<2x<0.65 (because it's closer to 6)
0.3<x<0.325

Since the thousandths digit of 2x is 2, then the thousandths digit of x is 1 or 6, so the decimal could be 0.301, 0.302, 0.311, 0.312, 0.321

Hope this helps :)

You go to the outlet mall with a friend and buy a jacket for $49.00 and new Vans for $55.00. Sales tax in Texas is 8.25%. How mu

Vlada [557]

Answer:

Amount spent after sales tax = $112.58

Step-by-step explanation:

Given that:

Cost of jacket = $49.00

Cost of new Vans = $55.00

Total spent = 49.00 + 55.00 = $104.00

Sales tax = 8.25%

Amount of sales tax = $\frac{8.25}{100}*104$

Amount of sales tax = $8.58

Total after sales tax = 104.00 + 8.58 = $112.58

Hence,

Amount spent after sales tax = $112.58
