Let s represent the number of students surveyed.
.. 0.40s play baseball
.. 0.60*(0.40s) play soccer and baseball
.. 0.60*0.40s = 12 . . . . . . . 12 students play soccer and baseball
.. s = 12/(0.60*0.40) = 12/0.24 = 50

Answer:
8.245*10^6
Step-by-step explanation:
scientific notation is known as c*10^n
c : any number from 1-10
n : the power of base 10
the number in our case between 1 and 10 is 8.245
but then we want to move the decimal 6 spaces to the right, so we multiply that by 10^6
The slope is 0 the equation of the line is y=3
We will use distribution
we will multiply 6 to each variable and number in the parenthesis.
6 times x plus 6 times 4
which is 6x +24
