Hey there!
1. To solve 9 x 5 , I could add the number 9 five times . . .
9 + 9 + 9 + 9 + 9 = 45
9 x 5 = 45 <----
2. I would use the same strategy as the first one, except add the number 8 five times . . .
8 + 8 + 8 + 8 + 8 = 40
8 x 5 = 40 <----
Hope this helps you.
Have a great day!
Step-by-step explanation:
5.14×10^6 + 7.2×10^5
51.4×10^5 + 7.2×10^5
58.6 ×10⁵
=5.86× 10⁶
It’s very easy to just times 40×10 and you get 400 and add $100 and you would get 500 so it would be 10 weeks
Answer: 10 weeks
Difference is 0.8333333333
If you are being asked to simplify, just combine like terms; such as, all the g’s and all the numbers so, your answer should look something like: 7g+6
