The temperature when Emily went to bed was -4°F.
Step-by-step explanation:
8°F + 3°F = 11°F (noon)
The temperature had risen by 3°F by noon. This means to add 3.
noon + 6°F = the day's high temperature
11°F + 6°F = 17°F (the day's high temperature)
The temperature rose another 6°F in the afternoon. This means add 6 to the temperature from noon.
high temperature - 21°F = temperature at bed
17°F - 21°F = -4°F
The temperature dropped by 21°F when Emily went to bed. This means to subtract 21 from the day's high temperature.
Risen, rose, and increase mean addition.
Decrease, dropped, and decline mean subtraction.
Hope this helps :)

The price of marked up candy is $6.00
perentage of mark up is 300%
let the marked up amount be represented as x
let 300% mark up be represented as 3x
the equatiopn for finding the price before markup
can be represented as 3x-x=$6.
2x=$6
x=$3.
There all 9's therefore they all have the same value
Answer:
x = 23/16
Step-by-step explanation:
x + 1/16 = 3/2
Get a common denominator
x + 1/16 = 3/2 *8/8
x + 1/16 = 24/16
Subtract 1/16 from each side
x+1/16 -1/16 = 24/16 -1/16
x = 23/16
