Answer:its 5/2 <100
Step-by-step explanation:
Your answer is going to be A. 7 daisies being the 7, and 19 being the roses in a 7 to 19 ratio. Therefor, your answer is A
The freight train speed = 22 mph
The passenger train speed = 28 mph
Step-by-step explanation:
Assign the speed of the freight train as; <em>x </em>mph
Since the passenger train travels 6 mph faster than the freight train, its speed will be; (<em>x + 6</em>) mph
In 2 hours, the freight and passenger trains will have traveled (distance = speed * time);
2<em>x</em> and 2(<em>x + 6</em>) miles respectively
Both add up to 100 miles. Therefore;
2x + 2(x +6) = 100
4x + 12 = 100
4x = 88
x = 22
x + 6 = 28
The freight train speed = 22 mph
The passenger train speed = 28 mph
Answer:
X = (18, 0 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( , )
let the coordinates of X be (x, y ) then equate to the coordinates of midpoint
= 8 ( multiply both sides by 2 )
x - 2 = 16 ( add 2 to both sides )
x = 18
and
= - 2 ( multiply both sides by 2 )
y - 4 = - 4 ( add 4 to both sides )
y = 0
coordinates of X = (18, 0 )
