5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
Ricky jogged 6 miles on tuesday and 6 miles on friday
<em><u>Solution:</u></em>
Given that,
Rick jogged the same distance on tuesday and friday
Let "x" be the distance jooged on each tuesday and friday
He also jogged for 8 miles on sunday
Total of 20 miles for the week
Therefore, we frame a equation as,
total distance jogged = miles jogged on tuesday + miles jogged on friday + miles jogged on sunday
20 = x + x + 8
20 = 2x + 8
2x = 20 - 8
2x = 12
x = 6
Thus Ricky jogged 6 miles on tuesday and 6 miles on friday
Data:
Model: 41cm
Scale: 1cm/24feet
To convert the measure of the model to the real Tower you use the scale factor
The scale factor is 24ft/cm
To know the height of the Eiffel Tower you multiply the height in the model for the scale factor:
Then so, the height of the Eiffel Tower is 984ft
