Answer:
x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27°F or x(-∞,-27]
Step-by-step explanation:
The melting point of the substance is - 32.78°C, then the melting point in °F is given by
⇒
⇒
⇒ F = - 27.004°F
Again, the boiling point of the substance is 349.68°C, hence, the boiling point in °F is
⇒ F = 661.424°F
Therefore, the range of temperature in °F for which the substance will not be in liquid state will be x ≥ 661.424°F or x[661.424,∞) and x ≤ - 27.004°F or x(-∞,-27.004], where x is the temperature of the substance in °F. (Answer)
Answer:15-(-5)=20
20-(-12)=32
Step-by-step explanation:
2(6-7x) = -8(x+6)
multiply the numbers inside the parenthesis with the numbers outside of them:
12 -14x = -8x-48
add 12 to each side:
-14x =-8x -36
add 8x to both sides
-6x = -36
divide both sides by-6
x = 6
Answer:
Step-by-step explanation:
Amari ran 3/4 distance Mary ran
A = 3/4 M
Amari ran 12 miles
12 = 3/4 M Multiply by 4
12 * 4 = 3*M Combine
48 = 3M Divide by 3
48/3 = M
M = 16
So Mary ran 16 miles.
