Elena bicycles 7 ​km/h faster than Dennis. In the same time it takes Dennis to bicycle 57km, Elena can bicycle 78km. How fast does each bicyclist​ travel? Can you also show the formula for how you got the answer? If not, that's okay, but I am trying to learn.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

show us the triangle so we can answer it
