Answer:
2
Step-by-step explanation:
given the difference of twice a number and one is three to find "number" let the number be x
2x - 1 =3
2x = 4
x= 2
thus the number is 2
Answer: directly north
=============================================
Explanation:
A one quarter turn is 1/4 of 360 degrees, so it's (1/4)*360 = 90 degrees.
Three quarters of a full turn is (3/4)*360 = 270, or you could triple the 90 to get 90*3 = 270.
Rick starts facing directly east. Then he rotates 270 degrees clockwise to end up facing directly north. Refer to the diagram below.
Step-by-step explanation:
it is the ratio of y change / x change.
when we look at the points with integer coordinates, we see that whenever x increases by 1 unit, y increases by 2 units.
so, the gradient is
+2/+1 = 2/1 = 2
