Luisa wants to use place-value blocks to show 367+215. How many tens blocks will she need to show the sum by regrouping?

She will need 58 tens blocks but there is a leftover amount of 2 so that would be 2 ones as well.

Step-by-step explanation:

357+215=582/10=58.2  (2 is the remander and thats how I got 2 ones as well)

The correct option is;

The line of best fit is not reasonable because it has more points below it than above it.

Step-by-step explanation:

Here we note that there are a total of seven points in the scatter plot and there are five of the points below the line of best fit and just two above the line.

Of the five points below the line of best fit, four are just about touching the underside of the line while one of the two points above the line is just about touching the line.

The proper positioning of the line can be reviewed, therefore, with a line drawn through the four points presently touching the underside of the line of best fit.
