Answer:
k=-2
Step-by-step explanation:
7k-10=-8-4(k+6)
7k-10=-8-4k-24
7k-10=-32-4k
7k-10=-32-4k
11k-10=-32
11k=-22
k=-2
The equivalent ration for 6/9 would be 6:9
Answer:
see attachment
Step-by-step explanation:
The complex numbers in this table are the ones where a negative number is under the radical. The attachment has these circled.
So the sum of 17 and a number x means to add them on one side of the equals sign. The other side would be your 20.
17 + x = 20
Your numbers are 2, 3, 4.
The three consecutive numbers are x, x+1, x+2
The square of the first equals the third so x^2=x+2
Solve this quadratic as x^2-x-2=0
Factor into (x+1)(x-2)=0
So your answers are x=-1 and x=2
Since the question says they’re positive integers, use x=2
So the numbers are 2, 3, 4
