Answer:
ok
Step-by-step explanation:
2.5 and 2.500 could be alternative ways of writing this decimal although they will be equivalent to one another.....
Hope this helped
It’s pretty much a special way of writing an equation of a line. it’s another way of writing y=mx+b. it’s Ax+By=C where a b and c are all real numbers and a and b are both not 0.the requirements can depend on what your doing but technically they are real numbers they are most often used as integers and to keep the a positive.also a b and c are usually required to not share common factors
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.
