Let t and t+3 be Warren's first and second speeds, respectively. Then:
220/t=231/t+3
220t+660=231t
t=60 mph as his mean speed

What is y=4/5x+2 written in standard form

shepuryov [24]

Answer:

$4x-5y=-10$

Step-by-step explanation:

we know that

The equation of the line in standard form is in the form

$Ax + By = C$

where

A is a positive integer, and B, and C are integers

In this problem we have

$y=\frac{4}{5}x+2$ ----> equation of the line in slope intercept form

Convert to standard form

Multiply by 5 both sides

$5y=4x+10$

$4x-5y=-10$
