2+number won over 9+number played=1/2
number won=number played (number played means how many more past 9)
so
if n=number won=number played then
times both sides by (2)(9+n)
2(2+n)=9+n
distribute
4+2n=9+n
minus n from both sides
4+n=9
minus 4 from both sides
n=5
answer is 5
test
2+5=7
9+5=14
7/14=1/2
true
n=5
C is your answer
slope is 3.5
x = 0, y = 0
x = 1, y = 3.5
x = 2, y = 7
x = 4, y = 10
Answer:
D
Step-by-step explanation:
because the estimate of 52 is 50 and the estimate of 11 is 10 so there.
-24 and 3 multiply to -72 and add up to -21
