2|3x + 5| = -10 . Divide both sides by 2:
|3x + 5| = -5 ===>3x+5=-5 & -3x-5=-5 In both cases x=0
Answer:
The temperature in Kelvin corresponding to F degrees Fahrenheit is 
Step-by-step explanation:
Given : One can convert temperature from Kelvin into Fahrenheit using the formula
.
To find : What is the temperature in Kelvin corresponding to F degrees Fahrenheit?
Solution :
Temperature from Kelvin into Fahrenheit is given by,

Writing Kelvin in terms of Fahrenheit,
Subtract 32 both side,

Divide by 95 both side,

Add 273 both side,

Therefore, The temperature in Kelvin corresponding to F degrees Fahrenheit is 
A. C = 17h + 15
b. 83 = 17h + 15
-15 - 15 subtract 15 from both sides
68 = 17h
------------
17 divide both sides by 17
4=h
They cleaned the house for 4 hours
c. C = 20x
to do this last part, you would put both equations into the calculator under y=, then look at the table to determine when the price is the same. According to the calculator, the price is the same at 5 hours
The tangent half angle formula, one of several, is

We have θ is opposite 4 in the 3/4/5 right triangle so



Answer: 1/2
This is actually pretty deep. It says half the big acute angle in the 3/4/5 triangle is the small diagonal angle of the 1x2 rectangle. Similarly, the small acute angle in 3/4/5 triangle is twice the small diagonal angle of the 1x3 rectangle.
Answer:
no it is not 32.725 is 0.01 less than
