Answer: 
Step-by-step explanation:
Given
The temperature on the ground is 
temperature drop observed is 
The height of the plane is 
The total increase in height per
is
units
Temperature drop is

The temperature at that altitude is

Parallel lines have the same slope.
So the graph of [ y = 3x + any number ] is parallel
to the graph of [ y = 3x - 10 ] .
A means 7 10 times so it like 7x10 same with g 96x10
Answer:
180.0
Step-by-step explanation:
Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5
