Answer:
1/5 took the test (k12)
Step-by-step explanation:
Any rhombus has the same length for all for sides, so:
x + 14 = 3x +4
So, we get x = 5
Now, we can write
x + 14 = 8y
Since x = 5,
19 = 8y
so y = 19/8 = 2.375
<span>You can take any one of the equations and substitute the value of x or y in. The length is 19</span>
Speed of Tim = 60 miles/hour
Speed of Joe = 45 miles/ hour
Distance = Speed x Time
A 3 hours, Tim had travelled 60 x 3 miles = 180 miles.
At 3 hours, Joe had travelled 45 x 3 miles = 135.
The difference between the distances is 45.
Therefore, they were 45 miles apart after 3 hours.
I hope this is right.
