We have,
x+y:x-y=3:2
To prove that, x+ y : x - y = 3:2.
x+y=3
And,
x+y = 2
Adding (1) and (2), we get
x+y+x-y=3+2
⇒2x=5
⇒ x =
Put x = in (1), we get
+y=3
⇒ y=3-=
x+y:x-y=
=3:2
So, x+y:x-y=3:2.
Answer
Q11 is 50,3
Q12, 23,19
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
(because -4 is equal to -4 and meets the condition of the top inequality, you plug in -4 into the top function)
![g(-4)=\sqrt[3]{(-4)+5}\\\\g(-4)=\sqrt[3]{1} =1](https://tex.z-dn.net/?f=g%28-4%29%3D%5Csqrt%5B3%5D%7B%28-4%29%2B5%7D%5C%5C%5C%5Cg%28-4%29%3D%5Csqrt%5B3%5D%7B1%7D%20%3D1)
Answer: What you would have left is 12 pieces of pie
Step-by-step explanation: As stated in the question, one pie has been sliced into 8 pieces, and there are three pies in all. That means we had at the beginning 3 x 8 slices of pie which equals 24 pieces.
Also if each pie had been sliced into 8 pieces then each can be represented as 8/8. Therefore eating one slice would leave you with 7/8 (that is 8/8 minus 1/8).
So, each of the three pies now have the following left overs;
1/2, 3/8 and 5/8.
Adding them all together would give,
1/2 + 3/8 + 5/8
Using 8 as the common denominator
4/8 + 3/8 + 5/8
(4 + 3 + 5)/8
12/8.
Therefore, there would be 12 pieces left altogether, which can also be expressed as one pie and 4 pieces.
Assuming you can’t use the same topping twice,
10 x 9 x 8 = 720
