Answer:
2, 3
Step-by-step explanation:
If the first integer is x, then the second is x+1. The given relation is ...
x +3(x+1) = 11
4x = 8 . . . . . . . . subtract 3
x = 2 . . . . . . . divide by 4
The integers are 2 and 3.

2 + 3(3) = 2+9 = 11
Answer:
Since speed is given in terms of "hours" we must convert 9 minutes to hours:
9 minutes = 9/60 hours = 3/20 hours
.
Let x = time (hours) it takes car to pass the truck
then
60(x + 3/20) = 69x
multiplying both sides by 20:
60(20x + 3) = 1380x
1200x + 180 = 1380x
180 = 180x
1 hour = x

Answer:
136
Step-by-step explanation:
The sum of interior angles of a polygon is (n-2)x180 where n is the no. of sides. Here n=5 Therefore sum of int. angles = (3-2)x180= 3x180=540.
Sum of all given angles =404.
Remaining angle= 540-404=136
Answer:
The width of rectangle is cm and length is cm.
Step-by-step explanation:
Let,
Width of rectangle = w
Length of rectangle =
Perimeter of rectangle = cm
Perimeter = 2(Length + Width)
Dividing both sides by 4
Width of rectangle =
The width of rectangle is cm and length is cm.
