21=3*7
28=2*2*7
gcf: 7
21w+28=7(3w)+7(4)=7(3w+4)

1/3p-2/3=1/3p+(-2/3)=1/3(p)+1/3(-2)=1/3(p-2)

12/6=2
-42/6=-7
12y-42=12y+(-42)=6(2y)+6(-7)=6(2y-7)
Point slope form is y-y1=m(x-x1)
where y1 and x1 represents the (x,y) point
Where m represents the slope
We need the slope and one point which you have given : m=2 (5,-5) —> x=5 y=-5
Y-(-5)=2(x-(5)) which simplified is
**Y+5=2(x-5)**
Hey there, the formula is A=a², and P=4a. Let's solve for a, A=1/16p²=1/16*12²=9cm², Therefore, the answer is 9 cm 2
For this case, the first thing we must do is define variables:
p: plane speed
w: wind speed
With the wind in favor, the speed is:
With the wind against the speed is:
Rewriting both equations, we have the following system of equations:
Then, solving the system of equations (graphically for example), we have the solution is:
Therefore, jet stream's speed:
Answer:
A) p + w = 960; p - w = 600; jet stream's speed = 180 km / h
Answer:
250 feet per minute
Step-by-step explanation:
1000 divided by 4 is 250. You divide them by each other because if you multiply 250 feet by 4 minutes, you get 1000.
