just get the area for all of them and add legth time width
Answer:
-2x-7y=-4
Step-by-step explanation:
5x+-7x=-2x
-9y+2y=-7y
1+-5=-4
So -2x-7y=-4
Answer:
12 hours
Step-by-step explanation:
$3000 / 36hours / 10weeks = $8.33333333333
$3000 / 30weeks / $8.33333333333 = 12hours
Answer:
Time = 91.2 seconds
Step-by-step explanation:
Since, Tyler swims at a constant speed 5 meters every 4 seconds.
Relation between distance and time is always proportional.
Therefore, d ∝ t
d = kt
Here, k = proportionality constant
For d = 5 m and t = 4 seconds
5 = 4k
k =
= 1.25
So the relation is, d = 1.25t
Now we have to find the time taken to cover 114 m.
From the given relation,
114 = 1.25t
t = 
t = 91.2 seconds
