Respuesta :
First try: 10 dribbles,
Second try: 78 dribbles,
10x8=80,
80-2=78,
78+10=88
Answer:
Marnie has bounced basketball 78 times on the second try.
Step-by-step explanation:
Let the number of times ball dribble before first try be x and number of times of dribble before second try be y.
Total number of times ball dribbled after two tries = 88
x+ y = 88 ...[1]
After first try that before second try. she has 2 fewer dribbles than 8x.
y=8x-2...[2]
Putting value of y in [1], we gte:
x = 10
y = 8 × 10 - 2 = 78
