Subtract one equation from the other to eliminate <em>x</em> :
(<em>x</em> + 3<em>y</em>) - (<em>x</em> - 3<em>y</em>) = 7 - 1
6<em>y</em> = 6
<em>y</em> = 1
Answer:
A formula to express this would be:
60 = 32 + 4h
This simplifies down to 7 for h
Find the area of the base:
(1/2)(4)(5) = 10
Then find the area of one of the sides:
(1/2)(4)(10) = 20
There are 3 sides and 1 base therefore:
20(3) + 10(1) = 60 + 10 = 70sqft
Hope this helps :)
Unit walking rate in miles per hour = 5 2/3 / 2 2/3 = 17/3 / 8/3 = 17/3 x 3/8 = 17/8 = 2 1/8 miles per hour.
Unit walking rate in hours per mile = 1/ 17/8 = 8/17 hours per mile.
