Answer:
16 3/10
Step-by-step explanation:
Think about what fraction become .3 when put into a calculator 
that's a 3 in the tenths place in the decimal system so the fraction would be 3/10. Then finally add on the 16 
*an aside if this is wrong it it is possible that they have rounded 1/3 to one decimal place. (1/3 is usually .33333 repeating)

Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1 
7x + 5y = -66 --- Equation 2 
I will be using the substitution method to solve this. 
Substitute x = 2y - 4 into Equation 2: 
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate. 
14y - 28 + 5y = -66
Evaluate like terms. 
19y - 28 = -66
Isolate 19y. 
19y = -66 + 28
      = -38
Find y. 
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1: 
x = 2y - 4
x = 2(-2) - 4
Evaluate. 
x = -4 - 4 
x = -8 
 
        
             
        
        
        
Answer:
8y = -6
Step-by-step explanation:
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers. 
9 + (-15) = -6
Hope that this helps!
