he drew 2 cards
Step-by-step explanation:
because 4x3 is 12 and to get back to zero u would have to draw 2 red cards which are 6 each. so 4x3=12 and then 6x2=12 12-12=0
Answer: x = 560 miles/hr
Step-by-step explanation:
Let speed of first plane = x
Let speed of second plane = y
x-y =108 (first plane is faster)
It took first plane 2.25 hrs to be 1825 miles apart.
Distance moved after 2.25 hrs =2.25x
It took second plane 1.25 hrs to be 1825 miles apart
Distance moved after 1.25 hrs =1.25y
So 2.25x + 1.25y = 1825 --------1
Put x = 108+y in eqn 1
2.25(108+y) + 1.25y= 1825
243 + 3.5y = 1825
3.5y= 1582
y = 452
x = 108 + 452 = 560 miles/hr
Answer:
32 = <4
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the opposite interior angles
15+17 = <4
32 = <4
