To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.
        
             
        
        
        
Answer:
Option A
Step-by-step explanation:
Line EC splits the angle into two equal angles so it is an angular bisector of DEF.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
A=πr2
Circumference = 2πr
20π = 2πr
r=10
π=3.14
A=3.14 * 10^2
=314 cm^2
 
        
             
        
        
        
Answer:
Step-by-step explanation:
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem 
 
        
                    
             
        
        
        
First find out how many cm at in an foot then convert it over to cm or feet. Then compare. The larger number is the wider car.
