Answer:

110x-95xy+6

Explanation:

15x ( 7 - 5y ) + 3 ( 5y - x ) - ( 4x + 3 ) ( 5y - 2 )

expand:

105x-75xy+15y-3x-\left(4x+3\right)\left(5y-2\right)

simplify:

105x-75xy+15y-3x-(20xy-8x+15y-6)

open the brackets:

-20xy+8x-15y+6+102x-75xy+15y

110x-75xy-20xy+15y-15y+6

final answer:

110x-95xy+6

On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in mile
Anettt [7]

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Speed is the change in distance if a body with respect to time. It is expressed mathematically according to the question as t = 1/500 × d

To determine the time it will take to travel 800miles, we will substitute d = 800 into the modeled equation.

t = 1/500 × 800

t = 800/500

t = 8/5

t = 1.6
