I’m sorry I don’t know the length of JT however JE = 3.
Answer:
y= 4x − 7 or 0=0
Step-by-step explanation:
4x−y+−4x=7+−4x
Answer:
Consider the expression 
. q is called the quotient, a is is the dividend and b is the divisor.
Since q is a multiple of 6, then q has the form 
for some integer k.
Since a is a multiple of 9, then a has the form 
for some integer s.
Since b is a factor of 12, then if 12 can be expressed of the form 
, for c an integer. Then b has the form 
Replacing the preview expression in the initial expression we obtain:
Then 
is a equation to Isabel's problem.
Answer: it will take him 4.5 hours to cover same distance
Step-by-step explanation:
Marathon runner covered the whole distance in 4 hours running at a constant speed of 8.1 km per hour.
Speed = distance / time
Distance = speed×time
Therefore, distance covered by the marathon runner in in 4 hours, running at a speed of 8.1 km per hour is
8.1 × 4 = 32.4 kilometers
if he decreased the speed to 7.2 km per hour, the distance remains 32.4 kilometers. Therefore,
At 7.2 km per hour, the time it would take him to cover the same distance would be
Distance/ speed = 32.4/7.2 = 4.5 hours
