Answer: c < 19
Step-by-step explanation:
<span>Solve this by substitution:
</span>Solve 5x - 4y = -13 for x:<span><span><span><span>5x </span>− <span>4y </span></span>+ <span>4y </span></span>= -<span>13 + <span>4y </span></span></span>(Add 4y to both sides)
<span><span><u>5x </u></span>= <span><span><u>4y - </u><u>13 </u></span><u> </u> </span></span>(Divide both sides by 5)
5 5
<span>x = <span><span><span><u>4</u></span> y </span>+ -<span><u>13</u><span>
</span></span></span></span> 5 5

5x - 4y = -13, 8x +10y = 12 (enter both equations with a comma between them and it will solve for you and show you step by step.
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
First you do the 4.8 + 9.9.
This equals 14.7
then you add 14.7 to the 7.5.
You get 22.2.
There is your answer!
