The formulaF = 1.8C + 32 gives the temperature
in degrees Fahrenheit (F ) for a given
temperature in degrees Celsius (C ). There is
one temperature for which the number of
degrees Fahrenheit is equal to the number
of degrees Celsius. Write an equation you
can solve to find that temperature and
then use it to find the temperature

Yes, that's an interesting exercise.

The Celsius temp is  ' C ' .

The Fahrenheit temp is    1.8C + 32

If they're the same number, then       C = 1.8C + 32

Subtract  1.8C  from each side:  -0.8C =             32

Multiply each side by  -1 :            0.8C =            -32

Divide each side by  0.8 :                  C =          -32/0.8  =  -40 .

-40°F  and  -40°C  are the same temperature.

40° is  the temperature  for which the number of  degrees Fahrenheit is equal to the number  of degrees Celsius.

Step-by-step explanation:

Given : F = 1.8C + 32 gives the temperature  in degrees Fahrenheit (F ) for a given  temperature in degrees Celsius (C ).

To Find: There is  one temperature for which the number of  degrees Fahrenheit is equal to the number  of degrees Celsius. Write an equation you  can solve to find that temperature and  then use it to find the temperature.

Solution :

Given Formula :  F = 1.8C + 32

If number of  degrees Fahrenheit is equal to the number  of degrees Celsius

Then ,

⇒ -0.8C =32

Thus The equation we can use to find the temperature  for which the number of  degrees Fahrenheit is equal to the number  of degrees Celsius:

40° is  the temperature  for which the number of  degrees Fahrenheit is equal to the number  of degrees Celsius.

Carol makes 9 and one third cups of snack mix. She puts all of the snack mix into plastic bags. She puts two third cup of the snack mix in each bag. How many plastic bags does Carol need?

9 1/3 / 2/3
9 1/3 = 28/3
28/3 / 2/3
28/3 x 3/2
84/6

5x-2y=1
2x+y=4

(1,1)

Step-by-step explanation:

5x-2y=1

2x+y=4

Im gonna use substitution but you could also use elimination

2x+y=4

-2x     -2x

y=-2x+4

replace y in the first equation with the second equation

5x-2(-2x+4)=1

distribute -2

5x+4x-8=1

9x-8=1

+8  +8

9x=9

divide both sides by 9

x=1

then put x in for the equation fo your choice im gonna use the second one

2(1)+y=4

2+y=4

-2    -2

y=1

Hope this helps :))

What is 46.273 rounded to the nearest whole number

46

Step-by-step explanation:

We notice that the digit in the tenth's position is the number 2. This is less than the number 5, hence we have to round this number 2 down to zero, which results in the entire number being 46.

46 would be the answer but if you want more detail what are you rounding it off to, the tens?

Tickets to the movies cost \$12 for adults and \$8 for children. A group of 14 people went to the movies, and the tickets cost \$136. The system of equations models this situation, where x is the number of adults and y is the number of children.x+y=14
12x+8y=136
How many adults and how many children were in the group?
A.

B.

C.

D.

-12*/x+y=14
12x+8y=136

-12x-12y=-168
12x+8y=136
+--------------------
-4y= -32

y=8

x+y=14

8+y=14,

y=6
