The correct answers are Part 1: 7x + 12y 50, x,y 0; Part 2: 7; Part 3: 0: Part 4: 2 old and 3 new video games.
Step-by-step explanation:
Penny's parents gave her $50 to buy new video games.
Price of used games are $7 and new games are $12.
Let Penny buy x number of old video games and y number of new video games.
Part 1:
Total price she spent on buying the video games are 7x + 12y.
This amount should be less than or equal to the amount of money she possess. therefore 7x + 12y 50, x, y 0.
Part 2:
Maximum number of used game she can buy can be given when she spends all her money just on used games. Therefore y = 0. This implies x .
Thus the maximum number of used game she can buy is 7 where she does not buy any new game and has $1 left with her after the purchase.
Part 3:
Minimum number of new games that Penny can buy is zero. She can not buy any new games and spent all her money purchasing old games.
Part 4:
The possible combination in which she can purchase both the video games is 2 old games and 3 new games.
hope this helps
Answer:
One solution
Step-by-step explanation:
Let's solve your equation step-by-step.
p+9=2p−3
Step 1: Subtract 2p from both sides.
p+9−2p=2p−3−2p
−p+9=−3
Step 2: Subtract 9 from both sides.
−p+9−9=−3−9
−p=−12
Step 3: Divide both sides by -1.
−p
−1
=
−12
−1
p=12
Answer:
p=12
2 should be the answer
If we plug it in, it would be 3(0) + 2(0) + 2. The first two constants will be cancelled equaling zero, so all you have left is 2. So that should be the answer. Mark me brainliest
The coordinate point (3.5, 3.5), the reflection of the coordinate across the y-axis will form a pre image at (-3.5, 3.5)
<h3>Reflection of coordinates</h3>
If a coordinate (x,y) is reflected across the y-axis, the equivalent coordinate points will be given as (-x, y).
Using the translation for the reflections;
Give the coordinate point (3.5, 3.5), the reflection of the coordinate across the y-axis will form a pre image at (-3.5, 3.5)

Answer:
$0.45
Step-by-step explanation:
1 tin of beans-> $1.55÷3=$0.31
3 tins of beans-> $0.31×3=$0.93
4 tins of tomatoes-> $2.73-$0.93=$1.80
1 tin of tomatoes->$1.80÷4=$0.45
