First,, we need to insert the numbers in before we can start solving. This will change the expression to the following: 7(2)(5) ÷ 10 + 4(9) We are first going to begin solving this by calculating the expression 7 × 2 × 5 ÷ 10. We can start this solving this by multiplying 2 by 5. 7 × 10 ÷ 10 Any expression divided by itself equals 1,, so the expression changes to: 7 × 1 Any expression multiplied by 1 remains the same,, so add 7 back into the equation. 7 + 4 × 9 Multiply the numbers together. 7 + 36 Lastly,, add the numbers together to find your final answer. 43 Let me know if you have any further questions. :)
Well all you need to do is add them so 3.45 + 2.2 = 5.65 then add 0.055 to 5.65 which is 5.705 and last but not least, add 9.03 to 5.705 which is 14.735 which makes 14.735 how many miles she ran. Hope this helps
