Answer:
x=3.5
Step-by-step explanation:
1. Multiply 
18x-12=5x+30
2.  Move the x's to one side
12x= 42
3. Isolate the variable by dividing
x=3.5
 
        
             
        
        
        
I don't know if u can see it, but there. 
X=12
Y=15
Z=20
 
        
        
        
Answer:
18 and 6
Step-by-step explanation:
Rn = 6   Ratio numerator 
Rd = 2 Ratio Denominator 
Rs = Rn + Rd 
Rs = 6 + 2 
Rs = 8 
Ratio Sum 
a = 24 Amount to Divide 
M = a ÷ Rs 
M = 24 ÷ 8
 M = 3 Multiplier Ratio Division Calculation 
Rr = Rn × M : Rd × M 
Rr = 6 × 3 : 2 × 3 
Rr = 18 : 6

Answer:
y = -1/2 x + 2
Step-by-step explanation:
Which of the following equations describes the line shown below? Check all
that apply.
(-4, 4)
(2, 1)
The standard equation of a line is y = mx,+b
m is the slope
b is he y-inttercept
Get the slope
Slope m = y2-y1/x2-x1
Substitute the coordinate
M = 1-4/2-(-4)
M = -3/6
M = -1/2
Substitute m= -1/2 and (2,1) into y = mx+b
1 = -1/2(2)+b
1 = -1+b
b = 1+1
b=2
Get the equation
Recall y =mx+b
y = -1/2 x + 2
