Answer:
(-2,8)
Step-by-step explanation:
3x+3y = 18
2x+y = 4
Multiply the second equation by -3
-3(2x+y) = -3*4
-6x-3y = -12
Add this to the first equation
3x+3y = 18
-6x-3y = -12
-------------------------
-3x = 6
Divide each side by -3
-3x/-3 = 6/-3
x = -2
Now solve for y
2x+y = 4
2(-2) +y = 4
-4+y =4
Add 4 to each side
-4+4+y = 4+4
y =8
Answer:
(-2,8)
Step-by-step explanation:
3x + 3y = 18 (1)
2x + y = 4 (2)
(1) - 3(2)
3x + 3y = 18
-(6x + 3y = 12)
-3x = 6
x = -2
Using (2)
2(-2) + y = 4
-4 + y = 4
y = 8
The expression that can be used to determine the total bill is 1.20 x ($47.60)
The total bill paid is the sum of the cost of the meal and the value of the tip.
Cost of the meal = $47.60
Cost of the tip = 0.20 x $47.60
Total cost of the meal = 1.20 x ($47.60)

The total number of cards including each pack after giving 3 cards from each pack will be 56.
Arithmeticoperators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variables called division.
Multiplication = to multiply any two or more numbers or variables called multiplication.
As per the given,
Total number of packs = 8
Number of cards in each pack is 10 so total cards = 8 x 10 = 80 cards.
He gave 3 cards in each so 8 x 3 = 24 cards.
Remainingcards = 80 - 24 = 56 cards
Hence "The total number of cards including each pack after giving 3 cards from each pack will be 56".

Answer:
Jerome has 50 baseball cards left.
Step-by-step explanation:
Jerome had 8*10 = 80 baseball cards total. He then gave his sister three from each of the ten packs (3*10 = 30).
Therefore, Jerome has 80 - 30 = 50 baseball cards.
