The total amount of calories burnt in jogging 2 miles = 185 calories
We have to determine the number of calories burned in jogging 3 miles.
Firstly, we will determine the amount of calories burnt in jogging 1 mile. We will use unitary method to evaluate this.
So, the total amount of calories burnt in jogging 1 mile = 
= 92.5 calories
So, the amount of calories burnt in 3 miles = 
= 277.5 calories
Therefore, 277.5 calories are burned in jogging 3 miles.
If a number's ten digit is 
and the units digit is 
, then you can write the number as 
.
Obviously, inverting the digits would lead to the number 
.
Since this new number is 36 less than the original, we have
Since we also know that the digit in the tens place is three times that in the units place, we can add an equation to form a system:
And thus 
Answer:
x<-2
Step-by-step explanation:
Answer:
4×5
3×2
Step-by-step explanation:
a+b=8 or a=8-b
4a+2b=26
4(8-b)+2b=26
32-4b+2b=26
32-2b=26
32-26=2b
6=2b
b=3
a=8-3
a=5
