Answer:
x = 18 y = 10
Step-by-step explanation:
let the first number be x
let the second number be y
x = y + 8..... equation 1
2x + y = 46.... equation 2
x is the larger number
y is the smaller number.
Rearrange the equation and add equation 1 to equation 2.
x - y = 8
+ 2x + y = 46
-------------------
3x + 0 = 54
3x = 54
divide both sides by 3
x = 54/3
x = 18
Substitute x = 18 into equation 1
x = y + 8
18 = y + 8
collect like terms
y = 18-8
y = 10
Answer: 
Step-by-step explanation:
The average speed of the car is 40 miles per hour:
The car drives for 45 minutes:
Since 1 hours has 60 minutes, we can convert the time from minutes to hours:
Knowing these values, we can use the following formula for calculate the distace "d":
Therefore, substituting values into the formula, we get:
