The temperature in the morning was -3°F. The temperature dropped 11 degrees by sunset. What was the temperature at sunset?

 -14 degrees F

Explanation:

Draw a vertical number line. Plot -3 on that line. Then move down 11 units to arrive at -14. Think of it like being in basement level 3 of a building, going down 11 floors, to get to basement level 14.

-14F°

Step-by-step explanation:

Given:

Original temperature (morning) = -3F°

Change of temperature = dropped 11F°

Solve:

The word "drop" here means lower in temperature, so basically, it is a negative change.

Sunset = Original + Change

Sunset = (-3) + (-11)

Sunset = -14F°

Hope this helps!! :)

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
