Answer:
5
Step-by-step explanation:
def is similar to abc so the 7.5 side is 1.5x bigger so divide 7.5 by 3 and multiply by 2
 
        
             
        
        
        
If rounded to the nearest 100,000th it would be 600,000
if rounded to the nearest 10,000th it would be 550,000
<span>if rounded to the nearest 1,000 it would be 553,945</span>
        
             
        
        
        
Answer:
88
Step-by-step explanation:
The original number ⇒ 100
100 is increased by 10%
The result is 20% reduced.
Calculate increase.
100 × (1 + 10%)
100 × (1.1)
= 110
Calculate decrease.
110 × (1 - 20%)
110 × 0.8
= 88

Answer:
-1(4c+1)(c-5)
Step-by-step explanation:
First get rid of the negative by factoring out -1, then determine what factors of 5, the constant term(the number without the x), multiply by 4 to add up to -19. The only factors of 5 are 1 and 5, so we will use these. (4c+1)(c-5) can be "foiled" to check our answer.
