3x +4y = 8
y = 3/4x - 2
Substitution Method
3x + 4(3/4x -2) = 8
Distributive Property:
3x + 3x -8 = 8
Simplify:
6x -8 = 8
Add 8 to each side:
6x = 16
Divide both sides by 6"
x = 16/6
x = 2 2/3
Now replace x with that and solve for y:
y = 3/4(2 2/3) - 2
y = 2-2 = 0
y=0
Answer:
the answer is B or at Least I think
Answer:
Luis wants to buy a skateboard that usually sells for $79.99
all merchandise is discounted by 12% = 0.12
Discount amount = sale price * discount percentage
= 79.99 * 0.12 = 9.5988
Selling price after discount = 79.99 - 9.5988 = 70.3912
Now we apply sales tax for the price after discount
sales tax of 6.75 % = 0.0675
Tax amount = price after discount * tax percentage
= 70.3912 * 0.0675= 4.751406
the total cost of the skateboard = Price after discount + tax amount
=70.3912 + 4.751406 = 75.142606
$75.14 is the total cost of the skateboard
