30 = 3/5
so 1/5 = 10 miles
there are 20/5 in 4 inches
10*20 = 200
they are 200 miles apart
The total price with sales tax is $ 246.1
<h3><u>Solution:</u></h3>
Cost of cellphone = $ 210
Cost of battery charger = $ 15
Cost of batteries = $ 5
So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries
Total cost = 210 + 15 + 5 = $ 230
Given that sales tax is 7%
sales tax = 7% of total cost
sales tax = 7 % of 230

Total cost including sales tax = 230 + 16.1 = $ 246.1
Thus the total price with sales tax is $ 246.1

4w + 9( -6 - 3w)
Expand brackets.
4w + 9(-6) + 9(-3w)
4w - 54 - 27w
Combine like terms.
4w - 27w - 54
<u>-23w - 54</u>
10. Answer is 9 . (51 - 6) / ( 3.5+5.5)
11. 5x-18 - 4x = -36
