Answer:30
Step-by-step explanation: Put 30 times 15 into a calulater. Then do 15 times 2 then you find your answer.
B and F
the x coordinates shift one to the right, so that's B.
the image flips over the x axis so the y coordinates become negative
Answer:
57.78 km/hr
Step-by-step explanation:
Total time taken, t = 6 hours
Total distance covered, d = 520 km
Distance by car = 260
Distance by train = 520 - 260 = 260 km
Train speed = x
Car speed = 2x
Average speed speed = 3x /2
Speed = distance / time
1.5x = 520 / 6
9x = 520
x = 520 / 9
x = 57.777
Average speed of train = 57.78 km/hr
Y=11 x=13
It’s a rectangle so each angle equals 90
1
Angle 1 + angle 2 =90
5y+2y+13=90
7y=77
y=11
Th diagnose of a rectangle bisect so 8x-16=5x+23
3x=39
X=13
Triangle A is an Isosceles
Triangle B is Equilateral
Triangle C is Scalene
