All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°
102+39=141°
180-141=39°
x = 39°
 
        
                    
             
        
        
        
Answer:
z=7
Step-by-step explanation:
3z+5=4z-2
5=4z-2-3z
5=z-2
5+2=z
7=z
z=7
 
        
             
        
        
        
Answer:
24 ounces for 4.80
Step-by-step explanation:
to find unit cost divide price by amount
4.40/20=0.22
4.80/24=0.2
 
        
             
        
        
        
Take 75 kilmoeters That is 1250 meters per second
        
             
        
        
        
So we follow the format y=mx+c. we know the y intercept (c) is 2. the gradient is -1/2 which is a fraction. and then substitute
y=mx+c
y=mx+2
y= -1/2x +2
