Given that the ship was traveling for 4 mph faster heading west than south then let the speed of the ship heading south be x mph, the speed of the ship heading west will be (x+4) mph
the distance is given by:
distance=speed*time
distance heading south was:
x*4=4x miles
distance heading west was:
5(x+4)=5x+20
thus the total distance will be given by:
4x+(5x+20)=191
9x+20=191
9x=191-20
9x=171
x=171/9
x=19 mph
the speed the ship used to travel west was:
x+4
=19+4
=21 mph
So you use x = 2.
x-2 = 0
x+7=9
so (0,9) (x,y)
Answer:
28 + 30 + 42 = 100
Step-by-step explanation:
s=small number
s+ (s+2) + (s+2 +12) =100
3s +16 = 100
3s =84
s = 28
small 28
mediam 28+2 = 30
large 30+12 = 42
Answer:
x= 12
Step-by-step explanation:
180° = (3x - 6) + (8x + 4) + 50° because all interior angles of a triangle add up to 180°
180° = 11x +48°
11x = 132°
x = 12
1ST you do 12 divided by 100 = 0.12 then you multiply 15. 0.12 x 15 = 1.80 then you do $12-$1.80= $10.80. You get 15% is $1.80 off the original price. So $12 with the discount would be $1.80. S= $12-0.15*1.80
$16 with the discount would be $ 2.40.
$20 with the discount would be $ 3.00
$25 with the discount would be $ 3.75
I hope that helps.
I am sorry if it is wrong.
