If you use the first answer, the equation becomes 2x + 2y = 16. You could subtract this from equation Q to eliminate x.
The second answer makes equation P -2x - 2y = -16. You could add this to equation Q to eliminate x. You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.
Answer:
The answer is 36
Step-by-step explanation:
If you do 27÷3 you get 9. So if it's 4 weeks you just add 9 which is 36
80p = 80 cents
£1.50 = $1.50.
(changing the signs, that's it)
So if a small bottle is half the size of a large bottle, and is 80 cents.
Amir buys 4 bottles, so 0.80 * 4 = 320 = $3.20.
Now 4 small bottles is the same as 2 large ones, so if he bought 2 large bottles: $1.50 * 2 = $3.00.
$3.20 - $3.00 = 0.20 cents.
Amir would've saved 0.20
P.S. What is "p" in European money
From what I think of this question, i think of 9x37 and 8x37 OR 9/37 and 8/37. either way
8x37=296
9x37=333
9/37=0.2432
8/37=0.2162
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is 
.
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with is 
, where r is the radius.
We get 
take square root of both sides.
Hence radius of the given circle is r = 2.
