Answer:
60 degrees F
Step-by-step explanation:
To find the range of temperatures, find the absolute value of the difference of the temperatures. It doesn't matter in which order you subtract.
|56 - (-4)| = |56 + 4| = |60| = 60
You can subtract in the other order:
|-4 - 56| = |-60| = 60
Range: 60 degrees F
Answer:
C
Step-by-step explanation:
The recommended daily intake of a nutrients supplement for a certain age group is 800 mg per day.
Actully supplements needs vary from person to person plus or minus 50 mg.
This means the minimum value is 800 - 50 = 750 mg per day and the maximum value is 800 + 50 = 850 mg per day.
Let x mg be a possible daily amount of nutrients supplement. Then

Subtract 800:

This inequality can be rewritten using absolute value notation as
Answer:
40
Step-by-step explanation:
remember PEMDAS
our equation looks like tihs: 
1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.
so now our equation looks liek this 
now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this:
6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.
Answer:
x=6.5
Step-by-step explanation:
2x+3=16
2x=16-3
2x=13
x=13/2
x=6.5
