Answer:
D
Step-by-step explanation:
Yess, such fun so
q=number of quarter
n=number of nickles
q+n=63
9.15=915 cents
25 cents=1 q
5 cents=1 n so
915=25q+5n
915=5(5q+n)
divide by 5
183=5q+n
we also have q+n=63
subtract q from both sides
n=63-q
subsitute 63-q for n in second equation
183=5q+63-q
add like terms
183=4q+63
subtract 63 from both sides
120=4q
divdie by 4
30=q
there were 30 quarters
subsitute
63=30+n
subtract 30
33=n
30 quarters
33 nicles
21 + -12x=0 I think that is the solutiuon

Answer:
29/61
Step-by-step explanation:
okay, first imma simplify the question a little bit.
122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.
okay now let's find the number of students who chose running
122 - 46 - 18 = 58
now, I'll find the probability
P(Running) = 58/122 = 29/61
