Answer:
Step-by-step explanation:
Add the like term
Here -10x , -3x are like terms
15 , 2 are like terms
Bring the like terms together.
-10x + 15 - 3x + 2 = -10x - 3x +15 +2
= -13x + 17
It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.
Step-by-step explanation:
Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.
Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.
x = distance to be covered / distance being traveled every hour
= 420 / 135 = 3.11 hours
We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.
Answer:
392000
Step-by-step explanation:
8*10^4 = 80000
4*10^6= 4000000
4000000 - 80000 = 392000
Answer 5!
Explanation;;
your dividing 15 among 3 people. Since 3 x 5 is 15, then when you divide you should get 5. 5 + 5 + 5 is 15!

Find the lengths AB, BC and AC.
length AB= √(4²+(-4)²) = √32
length BC = √(4²+7²) = √65
length AC = √(8²+3²) = √73
From the lengths of this triangle it can be seen that no side is equal to the other and also it is not a right triangle.
So, triangle ABC is a scalene.
