Step-by-step explanation:
4.5C
Let the two numbers be x and y.
We have x+y=45
⇒ y= 45-x.
The two numbers multiply and get 121, so we have another equation:
x*y = 121 (1)
Plug y= 45-x in (1), we have:
x* (45-x)=121
⇒ 45x - x^2 = 121 (distributive property)
⇒ x^2 - 45x = -121 (multiply -1 on both sides)
⇒ x^2- 45x + 121= 0
⇒ x= 42.128 or x= 2.872
y= 45- 42.128= 2.872
or y= 45- 2.872= 42.128.
Because it does not matter what number, x or y, is larger, the two numbers are 2.872 and 42.128.
Hope this helps~
-2n-2
-------- =13
3
-2n- 2/3=12
Add 2/3 to both sides
-2n+ -2/3+2/3=12+2/3
-2=38/3
Divide both sides by -2
38
-2n -----
----- = 3
-2 ----
-2
The answer will be -19/3
Hope this help!
