it would be 40000000 because there there are 7 zeroes and then you and then you multiply the two twos together and then put it in the front.
I believe it's the 3rd one. It's a really tricky question sorry if you get it wrong

Step-by-step explanation:
For rounding off to nearest tens, we compare the last digit.
Jiri is 22 years old and Pamela is 66
22•3=66

Answer:
9 and 6
Step-by-step explanation:
Write down the system.
The two numbers are x and y.
We are therefore given:
x+y=15
x-y=3
I will solve this for elimination since it is already setup for it.
I will add the columns since both equations are in the same form.
2x+0y=18
2x =18
Divide both sides by 2:
x =18/2
Simplify:
x =9
So if x+y=15 and x=9, then y=6.
The two numbers are 9 and 6.
Test:
9+6=15
9-6=3
