Answer:

Sam: 9, Amy: 13

Step-by-step explanation:

So five years ago, lets say Sam was 4, and Amy was 8. That would be half Amy's age. If we add on 5 to Sams age, as it says, Amy would then be 13, and Sam would be 9. This is also four years apart. Thus, the answers are Sam: 9 and Amy: 13

Answer:

Let's say that x is sam's age and y is Amy's age

x=y-4

and five years ago:

x-5=(y-5)/2

y-4-5=(y-5)/2

2y-18=y-5

y=13

x=9

then:

sam's age is 9 and Amy's age is 13

NikAS [45]
The total distance that Dominik will have to walk is the sum of the length of the escalator and the distance that the escalator has traveled. Let t be the time it will take him to reach the top of the escalator. The equation that best models the situation is,
                          225 ft + (82 ft/min) x t = (106 ft/min) x t
The value of t is 9.375 minutes.

y = 2x + 2

Step-by-step explanation:

find slope first

(4-0)/(1- -1) = 4/2

m=2

then use one of the points to solve for b

0 = 2(-1) + b, so b = 2
