<span>X+3y=10
X-5y=-2
--------------subtract
8y = 12
y = 12/8 = 3/2 = 1.5
</span><span>X+3y=10
x = 10 - 3y
x = 10 - 3(1.5)
x = 10 - 4.5
x = 5.5
answer
x = 5.5 and y = 1.5 </span>
So for this, we will be applying the <u>zero product property</u>, which is <u>"if a x b = 0, then either a = 0 or b = 0 or both a and b = 0"</u>. In this case, a = x + 13 and b = x - 7. Solve them separately:
<u>Your answer is x = -13 and 7.</u>
Answer:
Area = 
square feet
Step-by-step explanation:
The area of a rectangle is given by the formula:
A = length * width
Where length is 91 feet and width is 
feet
Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:
Hence,
So, the area is:
Area = square feet
Answer:
q(2)=20
Step-by-step explanation:
Substitute the 2 into the 10m, which will be 10(2). Then, multiply those two numbers, and you'll get 20
The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).
So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5
This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)
