Answer: Is it 31.4?
Step-by-step explanation:
5x2= 10 and 10 x 3.14= 31.4
(if by distances around you mean circumfernece)
Factors of 25: 5 x 5; sum = 10
Factors of 26 : 2 x 13; sum = 15
Factors of 27: 3 x 3 x 3; sum = 9
Highest sum is for the factors of 26. Thus, you should choose the number 26.
Answer:
x = 5 , y = 2
Step-by-step explanation:
5x + 2y = 29 ....................(1)
x + 4y = 13 Multiply this equation by -5:-
-5x - 20y = -65.................(2)
Add equations (1) and (2):-
-18y = -36
y = 2
Substitute for y in equation (1):-
5x + 2(2) = 29
5x = 25
x = 5
Check the results in the second equation:-
x + 4y = 13
5 + 4(2) = 13 - It checks out.
