Hey user!!!
first, we will find the distance between airport and origin then we will double it and we'll get the distance between airport and warehouse.
by Pythagoras theorem :-
let base be = 42 ( as given on abscissa )
and perpendicular be = 56 ( as given on ordinate )
hypotenuse is the distance between the airport and the origin.
therefore h² = 42² + 56²
=> h² = 1764 + 3136
=> h² = 4900
=> h = √4900
=> h = 70
hence, distance between airport and warehouse = 70 × 2 = 140 miles
now, it's given that the factory is 112 miles away from the warehouse in North.
hence, total distance travelled by the truck = 140 + 112
= 252 miles
correct option is 252 miles.
cheers!!!
The answer is wrong!
The correct answer is actually b!

Explainedddddd-
I think it’s 16 because 1/3=3/9 of hardcover books
3/9+4/9=7/9
2/9 is DVDS
72/9=8
8x2=16
Answer:
Each pencil costs $0.07 and each eraser costs $0.03
Step-by-step explanation:
System of linear equations
It refers to the study of systems when n variables are related in m linear equations, each one is not independent from the others. Solving such systems can be done following very diverse approaches.
Let p=the price of each pencil while e is the price each eraser
Julio bought 4 pencils and 3 erasers, spending

David bought 3 pencils and 4 erasers, spending

The system of equations is written in the form

We'll solve it by reduction. Multiplying the first equation by -3 and the second by 4:

Adding both equations:
7e=0.21
e=0.03
Multiplying the first one by -4 and the second by 3

Adding both equations:
-7p=-0.49
p=0.07
Solution: Each pencil costs $0.07 and each eraser costs $0.03
