Step-by-step explanation:
d= circumference/π
= 50/3.14
=15.9 cm
Answer: i would say no
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
Ax+By=C
Since x
is on the right side of the equation, switch the sides so it is on the left side of the equation.
3x=y
Move y
to the left side of the equation because it contains a variable.
3x−y=0

Answer:
after 7 minutes
19,600 feet
Step-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100x
y = 2800x
They can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.
