Javier rode his bike for a total of 40 minutes.
Let x be the minutes Javier ride after lunch
Let y be the minutes Javier ride before lunch
The number of minutes he rode after lunch is 4 times the number of minutes he rode before lunch
x = 4 y
The number of minutes he rode after lunch + number of minutes he rode before lunch = 40
x + y = 40
We know x= 4y
4y + y = 40
5y = 40
y = 8
x= 4y so x= 4(8) = 32
Javier ride 32 minutes after lunch
Hey there!
When two lines intersect, the pairs of angles that are directly across from each other (ex. the pair depicted in the image) are called opposite angles. These angles always measure the same.
This means that we can set the two expressions equal to each other and solve for x:
2x + 2 = 3x - 52
x = 54
Hope this helps!
Answer:
87.48
Step-by-step explanation:

you can pretty much count the units off the grid.
recall area of a rectangle is simply width*height.
