Barbara is converting 78°f to degrees celsius. first, she subtracts 32 from 78. what is the next step?
a.) multiply 46 by 5/9
b.) multiply 46 by 9/5
c.) add 273 to 46
d.) subtract 273 from 46

A.) Multiply 46 by 5/9

Step-by-step explanation:

The formula to convert Fahrenheit degrees to Celsius degrees is as follows:

So, converting 78°F to °C, according this previous equation is:

[Barbara subtracts 32 from 78]

 [Barbara multiplies 46 by 5/9]

or 25.56°C

A) multiply 46 by 5/9

Step-by-step explanation:

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
