Answer:
A. y<-3
Step-by-step explanation:
 
        
             
        
        
        
Solve for r in the first equation:
3(r+300) = 6
Use the distributive property:
3r + 900 = 6
Subtract 900 from both sides:
3r = -894
Divide both sides by 3:
r = -894 / 3
r = -298
Now you have r, replace r in the second equation and solve:
 r +300 -2 = 
-298 + 300 - 2 = 0
The answer is 0.
 
        
             
        
        
        
Answer:
a. 125
b. 25/64
c. 0.25
d. 343
e. 49/4
f. 0.81
Step-by-step explanation:
multiply by the same number by the amount of times the power tells you
b. 5*5 = 25         8*8= 64
c. 5*5 = 25         0.5*0.5 = 0.25
d. 7*7*7 = 343
e. 7*7 = 49         2*2= 4
f. 9*9 = 81        0.9*0.9= 0.81
