You have a 1/2 chance of spinning an even number on the spinner, and a 1/2 chance of rolling an odd number on the die, 1/2 times 1/2 give you a 1/4 chance of doing both of those tasks.
Answer: C
Steps: 4x + y = -4, x + y = 2
Isolate the x for (x + y = 2): x = 2 - y
Plug the value of x into the other equation: 4(2 - y) + y = -4
Simplify: -4y + 8 + y = -4
Combine like variables (letters): -4y + y = -3y
So -3y + 8 = -4
Subtract eight from both sides: -3y + 8 - 8 = -4 - 8
-3y = -12
Divide both sides by negative three: -3y ÷ -3 = -12 ÷ -3
Simplify: y = 4
Plug the value of y into one of the original equations (I'll use x + y = 2):
So x + 4 = 2
Isolate the x variable: x = -2

Step-by-step explanation:
-6x/-6 = -24/-6
x = 4
<span>Here we must calculate what percentage of the whole price is represented by the discount amount, which is the difference between the original price and the final one. Hence we have: DiscountedAmount = 440 - 154 = 286. And knowing that 440 constitutes 100% of the price, and 286 constitutes x% of it, we get that x = 286/440 <=> x = 65/100 or 65%. So the answer is D.</span>
