Answer:
Justin's average speed to his parents' house: x= 40mph
Justin's average speed from his parents' house: x+20=60 mph
Step-by-step explanation:
Let the average speed be x +20
Then average speed from his parents' x
And the distance is S=96
Then we know :
Justin's average speed to his parents' house: x= 40mph
Justin's average speed from his parents' house: x+20=60 mph
Answer:
To find the value of y, you need to isolate the variable. To do this, add 21 to -12. This gives you 9. Now, you're equation is set as 9 = y. This means that the value of y is 9.
Step-by-step explanation:
SA = 900cm^2
SA = 6×(s^2), where "s" is one side or edge of each square surface face
900 = 6s^2
150 = s^2
So each side is
The volume (V) of a cube is:
1. Split the second term in 6x^2 - 11x - 35 into two terms
6x^2 + 10x - 21x - 35
2. Factor out common terms in the first two terms, then in the last two terms
2x(3x + 5) - 7(3x + 5)
3. Factor out the common term 3x + 5
(2x - 7)
The car is traveling 0.5 miles per minute
