Answer:
131.3 miles
Step-by-step explanation:
The two cars are moving from different directions. The total distance between the two cars = 118 miles + 256 miles = 374 miles.
Let us assume that the two cars meet at point O, let the distance between car c and O be d₁, the distance between car d and point O be d₂, hence:
d₁ + d₂ = 374 miles (1)
Let speed of car d be x mph, therefore speed of car c = 2x mph (twice of car d). If it take the cars t hours to meet at the same point, hence
For car c:
2x = d₁/t
t = d₁ / 2x
For car d;
x = d₂/t
t = d₂/ x
Since it takes both cars the same time to meet at the same point, therefore:
d₁/2x = d₂ / x
d₁ = 2d₂
d₁ - 2d₂ = 0 (2)
Solving equation 1 and 2 simultaneously gives d₁ = 249.3 miles, d₂ = 124.7 miles
Therefore the distance from point of meet to Boston = 249.3 - 118 = 131.3 miles
This basically means 500 x 10. Unit form is just writing out the numbers. The answer is 5,000;
Answer:
x + |x| = 2x
Step-by-step explanation:
if the number is more than 0 or greater, then if you add it to itself, it will be equal to the value of two of the previous number. Hope this helps
= m^4 + 28m^2 - 36m^4 + 8m^5
= 8m^5 - 35m^4 + 28m^2
Answer
polynomial in standard form
8m^5 - 35m^4 + 28m^2
