Temperature can be measured in two different common units: degrees Celsius and degrees Fahrenheit. F(C) returns the temperature in degrees Fahrenheit as a function of the temperature in degrees Celsius C. F(C)=32+1.8C. Water freezes at 0 degrees Celsius. What is the freezing temperature of water in degrees Fahrenheit?

The freezing temperature of water in degrees Fahrenheit is 32.

Step-by-step explanation:

Hi, to answer this question we have to replace the value of the variable "C" in the formula F(C), by the value given in Celsius that water freezes.

Mathematically speaking:

F(C) = 32 +1.8 C

F (0) = 32 +1.8 (0)

Solving for F (Fahrenheit), since any number multiplied by zero equals zero:

F = 32

The freezing temperature of water in degrees Fahrenheit is 32.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
