Answer:
The equivalent expression for 
is 
Step-by-step explanation:
The distance in feet that Karina swims in a race is represented by 4d - 4, where is d is the distance for each lap.
To get equivalent expression we factor the expression 4d-4
Greatest common factor is 4
Factor out 4 from the expression 4d-4
when we factor out 4, we divide each term by 4
The equivalent expression for is
68 miles to 42.5's percent of decrease is: 37.5%
Using proportions. 68 miles - 42.5 = 25.5
25.5 x
------ = -----
68 100
Cross multiply:
25.5 x 100 = 2550
68 multiply x = 68x
2550 divided by 68 = 37.5
x = 37.5%
Answer:
If you pick the number 2, you will get (2) - 10 = 8
But the way he said it, it would be: (2) - 2 * 5 = 0
The correct way would be to write the expression: (x - 3) * 5
If 11/11 were to be equal to 1, then 22/11 will be equal to 2.
