it would be the second one because it is exactly the same the first one is a little bit shorter so there not exactly the same
I hope this helps you
42=4n-7n-7. (-9)
42=-3n+63
-3n=-21
n=7
18x^2+45x+27 is the answer
Answer:
Step 1 : First, solve one linear equation for y in terms of x .
Step 2 : Then substitute that expression for y in the other linear equation. ...
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.

Answer:
The answer is below
Step-by-step explanation:
a) The recipe for the meat loaf used by Jenny can serve a total of 8 people. Since there are 40 people in total to serve, the number of each ingredient needed is:
Number of each ingredient = total number of people / number of people served by one recipe
Number of each ingredient = 40 / 8 = 5
b) Since each recipe contains 1 1/2 lb (1.5 lbs) of ground beef, the total amount of ground beef needed to feed everyone is:
Total amount of ground beef = 1.5 lbs * 5 = 7.5 lbs
c) Since one serving would require 8 oz of milk. To serve everyone, the amount of milk needed is:
Amount of milk = 40 people * 8 oz = 320 oz
128 oz = 1 gallon
Amount of milk = 320 oz * 1 gallon / 128 oz = 2.5 gallon
