Answer:
20 and 16
Step-by-step explanation:
Let us find x and y.
x – y = 4 _____(1)
x/2 + y/2= 18___(2)
Multiply (2) by 2 and add to (1)
x - y = 4
+<u>(x + y = 36)</u>
<u>2x = 40</u>
=> x = 40 / 2 = 20
From (1):
20 - y = 4
=> y = 20 - 4 = 16
The two numbers are 20 and 16.
Answer:
d/2+9=(-15)
Step-by-step explanation:
-48
if you want me to explain, let me know in the comments !
You can simplify the expression by MULTIPLYING the exponents.
Example:
(2x^1)^5 = 32x^5
Is it necessary
Can I get it cheaper elsewhere
Will it last a while
These are just 3 I came up with. I do not know if they are what your teacher would have put.
