Step-by-step explanation:
So, Nora jobs 4 1/4 miles on Monday, which is 1 1/2 miles fewer than on Tuesday.
If this was 1.5 fewer miles, we need to add 1 1/2 and 4 1/4 to get our answer
We change the denominator on 1 1/2 to be 4. So, we multiply both sides by 2 and get 1 2/4
4 1/4 + 1 2/4 = 5 3/4
Answer:
It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.

Answer:
1000
Step-by-step explanation:
