3n+2n= 5n
22+38=60
180-60=60
60=5n
n=12
Total distance = 3km
Total distance left to walk = 3km - 500m - 1050m
Total distance left to walk = 3000m - 500m - 1050m
Total distance left to walk = 1450m
Total distance left to walk = 1.45km

8/5 = 1 3/5
(5 x 1 = 5 + 3 = 8, to get 8/5)
13/12 = 1 1/12 (12 x 1 = 12 + 1 = 13, to get 13/12)
Hope this helped! :D
Answer:
C. The square root of a number, positive or negative, is always positive. However, the cube of a negative number is negative.
Step-by-step explanation:
Of the choices offered, the one shown above is the only one that remotely makes any sense. Its description of square roots is erroneous, however.
The square root of a number n is the solution to the equation ...
x² = n
The function f(x) = x² has a range that only includes non-negative numbers, so the square root of a negative number does not exist. (Your answer choice says it is positive. It is actually non-existent among real numbers.)
On the other hand, the cube root of a number n is the solution to the equation ...
x³ = n
Since f(x) = x³ has a range that includes all real numbers, the cube root of n exists for all real numbers. (It is negative for negative values of n.)
