Tyler went to the supermarket to buy food for a food pantry. He has $36, and can carry up to 20 pounds of food in his backpack.
horrorfan [7]

Answer:

  • solutions: (2, 10), (4, 5)
  • non-solutions: all other points

Step-by-step explanation:

It can be useful to graph the inequalities related to Tyler's limits of money and weight.

  1x +3y ≤ 36 . . . . . . the limit on the cost of the items Tyler can afford

  1x +1.5y ≤ 20 . . . . . the limit on the weight of the items Tyler can carry

Then plotting the given points shows that only (2, 10) and (4, 5) are in the doubly-shaded area that is the solution space. The other points are not a solution.

Jayden wants to solve the equation n + 67 = 81. He writes the equation n + 67 - 67 = 81 - 67 to find the value of n. Will Jayden
Paladinen [302]
Hello there.

Question: <span>Jayden wants to solve the equation n + 67 = 81. He writes the equation n + 67 - 67 = 81 - 67 to find the value of n. Will Jayden get the correct answer using this equation? 

Answer: n + 67 - 67.
In this part of the equation the 67 would cancel out.
Which leaves n = 81 - 67.
This would get the correct answer to the equation.
Solving the equation meant that he would have to subtract 67 from both sides.
Which he has done.
Solving the equation:
81 - 67 = 14
n = 14.

</span>Hope This Helps You!
Good Luck Studying ^-^
