Answer: There is 17 marbles
Step-by-step explanation:
A: 4+8+5=17
B: 8
C: It has more marbles than the others.
Answer:
it's 1 dekameter (dam) = 10 meters you need to use that
Y = (2/3).x - 6. If y=0, then 0= (2/3).x - 6. Solve for x:
2x/3 - 6 = 0
Same denominator:
(2x - 18)/3 = 0
2x - 18 = 0
2x = 18 and x = 9 (x-coordinate)
