Answer:
19.1
Step-by-step explanation:
Answer:
150n is answer odd this q
Y = -2x + 4
6x + 3y = 6x + 3(-2x + 4) = 6x - 6x + 12 = 12
⇒ y = -2x + 4 == 6x + 3y = 12 ⇒ invinite solutions: 12
⇒ no solutions -12, -4, 0, 4
Answer:
The only option (0,0) is possible.
Step-by-step explanation:
Here in options four ordered pairs are given and they are (-3,-18), (-0.5,-3), (0,0) and (0.5,3).
Here, the x-values represent the number of books and the y-value represents the total weight of the books, in ounces.
Now, x must be 0 or a positive integer as it is the number of books.
Hence, the only option (0,0) is possible which means that the weight of zero books is zero. (Answer)
Answer: 13.722 km ; or, write as: 13 13/18 km .
___________________________________________________
Explanation:
___________________________________________________
Area = Length * width ;
___________________________________________________
or, write as: A = L * w ;
________________________
Given: A = 247 km² ;
L = 18 km ;
w = "y" ;
________________________
Find: "y"
______________________________
A = L * w ;
______________________________
Plug in our values:
______________________________
247 km² = 18 km * "y" ; solve for "y" (in units of "km") ;
_____________________________
18 y = 247 ;
___________________________________________________________
Divide each side of the equation by "18"; to isolate "y" on one side of the equation; and to solve for "y" :
___________________________________________________________
18 y / 18 = 247 / 18 ;
_____________________________________________
to get:
_____________________________________________
y = 13.7222222222222222...... km ; round to: 13.722 km
or; y = 13 13/18 km .
