3-digit number is abc. ( just call it)
abc= 9d + 3, meaning abc = 3e
abc = 2k + 1, meaning abc is an odd number
abc = 5t + 4, meaning c = 9 ( because abc is an odd number so c can not be 4)
so a+b must be equal 3.
abc can be 309, 219, 129
Answer:
1 1/4 pounds of strawberries.
Step-by-step explanation:
1 1/8 = 9/8
3/4 = 6/8
1 3/4 = 11/8
All added together equals 26/8.
4 1/2 = 36/8
36/8 - 26/8 = 10/8 = 5/4 = 1 1/4.
