Convert 59 degrees in Fahrenheit to Celsius temperature using the formula F=9/5c+32.
nataly862011 [7]

Answer:

15° C.

Step-by-step explanation:

To do this, we will need to plug in and solve.

59 = 9/5c + 32

Isolate the variable by subtracting 32 by both sides:

27 = 9/5c.

Divide both sides by 9/5, giving you:

15° C.

Due to the economy and not wanting to eliminate any jobs, all state employees were asked to accept a 4.5% reduction in their sal
jeka94

Answer: The secretary's salary prior to the reduction was $42,000.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The original secretary's salary (x) multiplied by the percentage reduction in decimal form (4.5/100) must be equal to the amount of the reduction (1890)

Mathematically speaking:

x (4.5/100)= 1890

Solving for x:

x (0.045)= 1890

x = 1890/ 0.045

x = 42,000

The secretary's salary prior to the reduction was $42,000.
