Ok? Is there like an equation or something that I can see so then I can help you?
Answer:
34 mph and 68 mph respectively
Step-by-step explanation:
Step one:
given data
let the speed of the first truck be x mph
and the speed of the second truck be 2x mph
time taken = 6 hours
total distance = 204 miles
Step two:
from speed = distance/time
distance= speed*time
hence
2x*6-6x= 204
12x+6x= 204
6x= 204
divide both side by 6
x= 204/6
x=34 mph
The second truck was moving at
=2x
=2*34
=68 mph
Answer:
y = - 
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= -
note the line crosses the y- axis at (0, 2) ⇒ c = 2
y = - x + 2 ← equation of line
Hello!
998 rounded to the nearest 10 is 1000. It is also 1000 when rounded to the nearest 100.
274 rounded to the nearest 10 is 270. 274 rounded to the nearest 100 turns it into 300.
