Given that Sara put 7 boxes in her closet.
So number of boxes = 7
Then it says that each box is for holding a different type of seashell. So far, there are 0 shells in each box.
So the number of seashell in 1 box = 0
We need to find about how many shells does Sara have.
To find that we will just multiply (number of boxes) by (number of seashell in 1 box). Which is given by 7 times 0.
we know that product of a number and 0 is always 0.
Hence final answer is 0 seashell.
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
Answer:
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.

Step-by-step explanation:
12x-8y=24
6x-y=21
---------------------
y=6x-21
12x-8(6x-21)=24
12x-48x+168=24
-36x=-144
x=144/36
x=4
y=24-21
y=3
