Distribute the two: 2x + 6 = 18
Subtract the six: 2x = 12
Divide by two: x = 6
That's your answer!
        
             
        
        
        
Answer:
Vertical angles are congruent 
Step-by-step explanation:
vertical angles intersect, usually forming a X shape, and have to always be equal 
 
        
             
        
        
        
Answer:
No
Step-by-step explanation:
To represent an exponential function, then it must be "y = a^x" where a is any real number, and x is just x.
 
        
             
        
        
        
If
N = a (mod 10)
N = b (mod 13)
gcd(10,13) = 1
then 
N = 10 bx + 13 ay (mod 130)
Where
10x + 13y = 1
<span>-> </span>(10x + 13)
(mod 2) = 1 (mod 2)
<span>-> </span>y (mod 2) = 1
y = -3, x = 4
-> N = 40b – 39a
(mod 130)
 
It is given that  ra + sb
should be non-negative:
 
N = 40b – 39a (mod 130)
N = 40b + (130 – 39)a (mod 130)
N = 40b + 91a (mod 130)
 
Therefore, N modulo 130, in terms of a and b is: <span>N = 40b + 91a
(mod 130).</span>
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
Given
V = πr²h
Rounding to the nearest whole number gives
π ≈ 3
r ≈ 4
h ≈ 6
Then
V = 3 × 4² × 6 = 3 × 16 × 6 = 288 in³
