(x/-3)+2=39
minus 2 both sides
(x/-3)=37
times both sides by -3
x=-111
Answer:
the snail travels 30 mm per minute
Step-by-step explanation:
Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.
the snail travels 30 mm per minute
Answer:
66 2/3 mL
Step-by-step explanation:
Let v represent the volume in mL of added 30% solution. Then the amount of salt in the mix is ...
0.10×100 +0.30×v = 0.18(100 +v)
0.12v = 0.08(100) . . . . .subtract (0.18v +0.10×100)
v = 8/0.12 . . . . . . . . . . . divide by the coefficient of v
v = 66 2/3 . . . . mL
Adding 66 2/3 mL of 30% salt solution to 100 mL of 10% salt solution will make 166 2/3 mL of 18% salt solution.

Answer:
Option A) The temperature of F degrees Fahrenheit converted to degrees Celsius
Step-by-step explanation:
The formula to convert temperature from degrees Fahrenheit to degrees Celsius is:
If we have the measure of temperature in degrees Fahrenheit we can convert that temperature to degrees Celsius by substituting it in place of F. For example, if we want to convert 50 degrees Fahrenheit to degrees Celsius just replace F in the above formula by 50 and C(F) will give the equivalent temperature in degrees Celsius.
So, C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius. Option A gives the correct answer.
