Mike started the trip at 2 : 45
______________________
So, if you want to find the answer you have to subtract the 2 times
3 : 28
-
43
=
2 : 45 3 : 28 - 3 = 3 : 25 - 40 = 2 : 45
Answer:
y=50.
Step-by-step explanation:
The sum of all angles of a triangle will always be 180 degrees, so if you take the angles of the larger triangle you get 130. the other angle then must be 50 because 50+ 130=180.
Let the width of the rectangle be x
then the length is x+2
we are given the area as 80 square meter
and we know the area of a rectangle is given by
area=L*W
area=(x+2)*x
but our area=80
80=(x+2)*x
x^2+2x=80
x^2+2x-80=0
we use the quadratic formula to solve this which gives us
x=8
therefore our width is 8
and our length is 10
4
Because u multiply 2 by 4 =8 and 8 is less than ten the sign represents less than or equal to so 8
