Help step by step I don’t understand(:

Answers

it is a because each day you run 5 miles, meaning 100 miles is decreasing since you keep running the miles away, for example if you ran for 4 days 100-20, because we multiplied 4x 5( the amount of miles) and now we would have 80 miles to go

It would have to be the first option.

The second option is not correct because you are not adding more than what her goal is.

The third option is not correct because you are not dividing from her goal.

The fourth option is not correct because it would ultimately result in a negative number.

The first option is correct because it subtracts how many days she has ran times 5 from her goal. The resulting answer would show how many miles she has left to reach her goal of 100 miles during that month.

Hope this helps!

How modeling partial products can be used to find the products of greater numbers

Answers

Partial product is a method of doing multiplication in math. The reason it’s called “partial product” or “partial answer” (the word “product” means answer in multiplication just like “sum” means answer in addition) is because you are doing many “parts” of a larger multiplication. To get to the final answer, you must add up all “parts”. Besides breaking down the multiplication process into parts, another focus of partial product method is to write the number into its place values. In other words, all numbers (with the exception of the number in the one value) will end in zero – which makes multiplication easier and faster. Here’s an example: 123 x 4 -------- Rewrite or breakdown 123 as 100 + 20 + 3 **The number 4 doesn’t need to be rewrite because it’s in the one value.** Multiply each of the above value to 4 and you get: 100 x 4 = 400 20 x 4 = 80 3 x 4 = 12 Add the products/answers together, and you’ll get = 492 Check your answer by multiplying 123 x 4 = 492 Here’s another example: 45 x 78 ------------- Rewrite 45 as 40 + 5 Rewrite 78 as 70 + 8 Multiply the top row of numbers to the bottom row of numbers: 40 x 70 = 2800 40 x 8 = 320 5 x 70 = 350 5 x 8 = 40 Add the products/answers together = 3510 Check your answer by multiplying 45 x 78 =3510 Hope this helps!

Answers

He buys 30 bottles which each costs 3 dollars. So 30 times 3 means he pays 90 dollars. Plus the 25 dollar handling fee which is 115. However the competing supplier is 4 dollars every bottle for the pint bottle. So if he bought 30 times 4 he would pay 120. That is without the handling money. So thats why he should stay with his
