The length of hypotenuse is 39.
Step-by-step explanation:
Given,
Vertical side = a = 15
Horizontal side = b = 36
Hypotenuse = c
Using pythagorean theorem
Taking square root on both sides
The length of hypotenuse is 39.

The given equations satisfy the given conditions. There are
2 equations and 2 unknowns, so a certain solution can be found.
This can be solved using substitution,
Substituting eqn 2 to eqn 1:
2(2y – 10) + 3y =1240
Simplifying,
y = 180
x = 350
His speed is 8 miles an hour. 2/3 x 12/1 = 24/3 = 8
Let 'T' be the number of hours after 8:00. ... Distance 'A' = 100 T. ... Distance 'B' = 160 (T-1.5). ... At the time when the later, faster train catches up with the earlier, slower one, the distances are equal. Write an equation that says they're equal, solve it for 'T', and add 'T' hours to 8:00.
Answer:
Because we are working with a variable (y) and we don't know what number it represents, we can only write down what the calculation would be, but we can't get the actual number answer.
15/y
