The 2 because we don't know if it is exactly two or if was was rounded up/ down to 2.
Answer:
1. z = 5, 2. w = 9
Step-by-step explanation:
1. 5z - 4 = 21
5z = 21 + 4
5z = 25
z = 25/5
z = 5
2. w/9 + 2 = 3
w/9 = 3 - 2
w/9 = 1
w = 1 x 9
w = 9
I hope this helps :)
3/4 = 45/60, 4/5 = 48/60, 2/3 = 40/ 60
14-8=6, so 8 balls balance with 6 balls and 20 grams. From this you know that 2 balls=20 grams, simply divide this by 2 to get the weight of one ball which will weigh 10 grams.
