If a temperature in degrees celsius is given as c, finding the sum of 1.8 times c and 32 gives the temperature in degrees fahrenheit. the temperature in degrees fahrenheit is given by , and 40°c is equal to °f.

The temperature in degrees Fahrenheit is given by

40°C is equal to 104°F

Step-by-step explanation:

We can find the formula to find the temperature in degrees Fahrenheit with the problem information, the temperature in degrees Fahrenheit is given by:

(1)

F: Temperature in degrees Fahrenheit

C: Temperature in degrees Celsius

Now, with the equation (1) e can find how many degrees Fahrenheit are 40 degrees Celsius.

We need to replace 40 °C in the equation (1)

F= 104 degrees Fahrenheit

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
