L= length
W= width
Perimeter= 2L + 2W
substitute the known numbers
34 ft= 2(8 ft) + 2W
34= 16 + 2W
subtract 16 from both sides
18= 2W
divide both sides by 2
9 ft= W
ANSWER: The width is 9 feet.
Hope this helps! :)
Answer:
4y/5+2x/5-12/5
Step-by-step explanation:
Equal, actually since you're stating that those 10 students hopped that total distance.
The expression for y in terms of "a" when value of x is doubled is 
<em><u>Solution:</u></em>
Given that,
y is directly proportional to 
Therefore,


Where "k" is the constant of proportionality
y = a for particular value of x
Therefore,
--------- eqn 1
We have to find when x is doubled
x is doubled means 2x
Let it be 
Hence we get,
--------- eqn 2
Substitute value of k from eqn 1, we get

Thus expression for y in terms of "a" when value of x is doubled is
