Estimate the sum of 672 and 830 by rounding to the nearest hundred before adding

1500.

Step-by-step explanation:

We are asked to find the sum of 672 and 830 by rounding to the nearest hundred before adding.

We can see that tens value in number 672 is greater than 5, so we will round up 672 to nearest hundred that is 700.

We can see that tens value in number 830 is less than 5, so we will round down 830 to nearest hundred that is 800.

Therefore, the sum of our given numbers would be 1500.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew
