Answer:
k = - 8
Step-by-step explanation:
Subtract 9 from both sides to get the constants on one side and the variables on the other
9 - 2k = 25
- 2k = 25 - 9
Simplify
- 2k = 16
Divide by -2 on both sides to isolate the variable, then simplify once more.
- 2k/ -2 = 16/ -2
k = 16/ -2
k = -8
Answer:
9
Step-by-step explanation:
n2-27=6n
Than n (exponet) 2 - 27 - 6n = 0
Now factor (n-9)(n+3)=0
Answer:
50% decrease
Step-by-step explanation:
I took the test
A 2 - - 7 = 9
b - 3 - - 4 = 1
c - 5 - 6 = - 11
d - 3 - - 5 = 2
Answer:
x+ (x+1) = 55
27, 28
Step-by-step explanation:
Let x = first number
x+1 is the next consecutive number
x+ (x+1) = 55
Combine like terms
2x+1 = 55
Subtract 1 from each side
2x+1-1 = 55-1
2x = 54
Divide by 2
2x/2 = 54/2
x = 27
The numbers are 27 and 28
