Answer:
stuff and more stuff
Step-by-step explanation:
Answer:
Country A = 84
Country B = 28
Country C = 18
Step-by-step explanation:
Country A, Country B, and Country C won a total of 130 medals;
A + B + C = 130 ......1
Country B won 10 more medals than Country C;
B = C + 10 .......2
Country A won 38 more medals than the total amount won by the other two;
A = B + C + 38 ........3
Substituting equation 3 to 1;
(B+C+38) + B+C = 130
2B + 2C + 38 = 130 .......4
Substituting equation 2 into 4;
2(C+10) + 2C + 38 = 130
4C + 58 = 130
4C = 130-58 = 72
C = 72/4 = 18
B = C + 10 = 18 + 10 = 28
A = B + C + 38 = 18 + 28 + 38 = 84
Country A = 84
Country B = 28
Country C = 18
Answer:
(a)180-135=45
45/360×100=12.5%
(b)135/360=27/72=9/24=3/8
(c)120/360×72=24
(d)180-120=60
60/360×72=12
I would appreciate if my answer is chosen as a brainliest answer
Total miles= rate x time
We can set up 2 eq:
24=(x+8)(y-4)
24=xy
Where x is equal to my original rate
and y is equal to the original time spent traveling the 2mi
We can now solve for one of the variables and find our rate
