I’m pretty sure it’s 9/10 - 2/5. I’m sorry If it’s wrong
First of all u draw a number line, then u labbel it, then go to zero, n count 6 negative steps, ok in simple terms move backwards thrice
Answer:
20.2 miles
Step-by-step explanation:
This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:
=
+ 
=
+ 
576 =
+ 169
= 576 - 169
= 407
x = 
= 20.1742
x = 20.2 miles
The glider has to fly 20.2 miles to return to the airport.
12x+1=-7
-1 -1
12x=-6
/12 /12
x=-1/2 or x=-0.5
Answer : The area of sector is,
