Answer:
A & D are correct
Step-by-step explanation:
to solve for 'x':
4x + 16 = 180
4x = 164
x = 41
m∡A = 2(41)+1 = 83°
m∡B = 41°
m∡C = 41+15 = 56°
22 miles,
30miles - 8 miles = 22 miles
Mikes trip to work is 22 miles farther than sam’s
The speed at which they are separating = 6.6 + 7.6 = 14.2 mph
time = distance / speed
time = 41.18 / 14.2 = 2.9 miles answer
Answer:
Step-by-step explanation:
d = r * t
Let the rate of the boat in still water = x
Let the rate of the stream = y
Against the current
24 = (x - y)* 4 Divide both sides by 4
24/4 = x - y
6 = x - y
With the current
24 = (x + y )* 3 Divide both sides by 3
24/3 = (x + y)
8 = x + y
Put the two equations together
x - y = 6
<u>x + y = 8</u> Add
2x = 14 Divide by 2
2x/2 = 14/2
x = 7
x + y = 8
7 + y = 8
y = 8 - 7
y = 1
The boat is going 7 miles per hour
The stream is going 1 mile per hour.
