Answer:
450
Step-by-step explanation: Multiply The Value By 100
Division is multiplication by the reciprocal. The reciprocal is when you see what times your fraction equals 1.
Here's your answer. Just simplify now.
7/8 * 4/9= 28/72
We need to build a system of equations:
a + b + c = 127......(1)
b - c = 13..............(2)
a - b - c = 41..........(3)
adding equations (1) and (3):-
2a = 168
a = 84
Substituting for in equation (1)-
84 + b + c = 127
b + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56
b = 28
Finally from equation (2)
c = 28-13 = 15
Answer is Country a had 84 points , b had 28 points and c had 15 points.
It means that -5 is the range of your answer, it will be less than that.
