37.5 grams of contaminants will remain after 4 hours.
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x + 2y = 7 into this form
Subtract 3x from both sides
2y = - 3x + 7 ( divide all terms by 2 )
y = -
x +
← in slope- intercept form
with y- intercept c =
→ C
So the equation is n/4-4=14
then you +4 to both sides
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
+4 +4
then to check your work
72/4-4=14
so N=72

Y= -5.8 is the correct answer
33 because they can do 3 things...<span>go up, go down, or stay unchanged and you have 11 so 3 x 11 = 33</span>
