Answer:
60 m/h
Step-by-step explanation:
S = d/t
S= 360/60
S= 60
Y - 1 = m(x - 1) . . . (1)
y = mx - m + 1 . . . (2)
From(2), -m + 1 = 2 => m = 1 - 2 = -1
Substituting for m in (1), we have:
y - 1 = -(x - 1) . . . (3)
Equation of a line in general form is given by ax + by = c
From (3), y - 1 = -x + 1
x + y = 1 + 1
Therefore, required equation is x + y = 2.
Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.
Ok so BFD is a 90 degree angle. So you know you have 43 in one of the spaces so that means all you have to do is take 90 and minus 43 which is 47.
The diagonals of a rectangle are congruent ⇒
4d - 1 = 3d + 4
4d - 3d = 4 + 1
d = 5
