By writing an equation you can easily solve this:
18+ X + 4X - 1 = 42
•we need the answer to 4X-1
1. put the parts that include the X parameter in one side and the integer numbers in one side :
X + 4X = 25
5X= 25
X= 5
2. 4X-1 —> 4x5-1 = 19
Answer:
D
Explanation Given:
if you plug in 1 for x then y=(3)^2
(3)^2=9
you have your two coordinates. (1,9)
It would take you 15 minutes. Since one hour equals 60 minutes your equation would look like this:
4x=60
So you need divide 4 into both sides in order to find the value of x which represents one mile.
So one mile takes 15 minutes to walk or x=15.
