Answer:

Step-by-step explanation:
First open the brackets

Then collect the like terms

Solve the like terms

The simplified form is

Answer:
1. 3/5=60%
2. 4 remaining in the bag
3. 2 marbles remain in the bag
4. 2/4=1/2=50%
First let's find the result of the sum:
30 + 40 + 70 = 140
Now let's review the operations of each one:
Jillian added 30and40and then 70:
30 + 40 = 70
70 + 70 = 140
Samuel added 30 and 70 and then 40
30 + 70 = 100
100 + 40 = 140
answer
both are correct.
Conclusion: the order of the factors does not alter the product.
