By taking <span>logarithmic of base 10
∴ </span><span>

∴ x log 4 = log 64
∴ 

note: we don't need to write the base in case of the base =10
∴ The correct choice is 
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>
 
        
                    
             
        
        
        
Answer:
The answer is A) -9.272
Step-by-step explanation:
-5.872 + (-5.1)/1.5
= -5.872 - 3.4
= -9.272 
 
        
             
        
        
        
C. 6/5 * 4
6/5 = 1.20 where .20 represents the 20% increase in serving.
1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%
4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups
        
             
        
        
        
7. 3/4 x 12 is 9 so subtract 9/12 from 12/12 to get 3/12
8. Their pizzas were all cut differently. Josh’s pizza was cut in half, Lisa’s was cut into 6 slices and Vicki’s was cut in 8 slices
        
                    
             
        
        
        
Any rational number will satisfy the situation.
