Which rounding strategy will result in the most reasonable estimate for the expression −148+297+−546+151+48? −150+300+−550+150+50=−200

−100+200+−500+100+0=−300

−100+200+−500+100+0=−900

−150+300+−550+150+50=−1200

-150 + 300 - 550 + 150 +50 = -200

Step-by-step explanation:

I rounded to the nearest tens place for each number.

e) none of the above because the measure of angle cba is 101°

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
