Answer:
54=12+r
Step-by-step explanation:
'Sum' means to add.
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The vertex B is at (1, 5), then vertex B' is at (-2, 11).
<h3>What is a triangle?</h3>
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.
∆ABC is translated 6 units up and 3 units left to create ∆A'B'C'.
The vertex A is at (-1, 2), then vertex A' is at,
A' = (-1-3, 2+6) = (-4, 8)
The vertex B is at (1, 5), then vertex B' is at,
B' = (1-3, 5+6) = (-2, 11)

Answer:

Step-by-step explanation:

(Multiplying each of the numbers also yields 240)
Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes
The answer would be 1 1/2 think of it as 3-2 and then 5/8 - 1/8
