Answer:
<h2>
1613.3 feet </h2>
Step-by-step explanation:
Given the conversion 1mile = 5280feet
If a bicycle is traveling at 20 miles per hour, then the bicycke must have been travelling at (20*5280)feet per hour which is equivalent to 105,600 feet per hour.
To know the number of feet that will be covered in 55seconds, we will solve the equality operation;
If 105,600 feet = 1hour (3600secs)
x foot = 55secs
where x is the amount of feet it will cover in 55 seconds?
Cross multiply
3600 * x = 105,600*55
3600x = 5,808,000
divide both sides by 3600
3600x/3600 = 5,808,000/3600
x = 1613.3 feet (to the nearest tenth)
<em>Hence the amount of feet covered in 55seconds to the nearest tenth is 1613.3 feet </em>

Answer:
x = 4
Step-by-step explanation:
Firstly we have to distribute: 2x + 4x + 6x -2x - 6 = 34
Collect like terms: 10x - 6 = 34
We have to isolate x to get it's value: Add 6 to both sides
10x = 40
Divide both sided by 10: x = 4
