Question

Can anyone please help me with these math problems I need it for tomorrow

Answer 1

I hope this helps!

25 is 7.8
26 is 8.3
27 is 14.5
28 is yes, they both ran the same distance because 7×5 is equal to 5×7. They both equal 35. So, both ran the same distance.

Answer 2

For the 1st one it would be 7.8. This is because 7+0=7 and then adding a decimal when it is 0.8 as in your problem you add the 8 to the end not the beginning. The second one is 8.3 because anytime you multiply by 1 you get the same number. For the third problem you add what is in the parentheses  because in PEMDAS you always start with parentheses. So, 4+7=11. Next, you will add 11 and 3.5 which is 14.5. I hope this helps!
