Answer:
18, because if each child had 3 pieces that is 9 each and then 9 + 9 = 18
Step-by-step explanation:
Asleep. 6/16 Simplified would be 3/8
Awake. 10/16 Simplified would be 5/8
How I did it was by using the amount that was asleep and awake as numerators and the TOTAL is 16 so that is the denominator.
Hope this helps, let me know if you have any questions, have a good day!
I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12
The sum of 3a²-a-3 and 2a-9 is 3a²+a-12
3a²+a-12 - (a²-3a-7) = 3a²+a-12 - a² + 3a + 7 =
2a² +4a - 5
