Explain how to estimate 368+231 in two different ways

Estimate the sum in two different ways:

A) By rounding off to the highest place value (hundreds):

 368 = 400  (3 hundreds is the highest place value)

 231 = 200 (2 hundreds is the highest place value)

 400 + 200 = 600

B) By rounding off to the second highest place value (tens):

   368 = 370

   231 = 230

   370 + 230 = 600

Hope this helps!

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
