Subtract 3 from the right and do the same to the left which leaves you to x = -1
Answer:27x^6 /16
Step-by-step explanation:27x^3 x x^7 divided by 16x^4
then simplify the expression which will be 27x^3 x x^3 divided by 16
then calculate the product which is x^3 x x^3 which is x^6 so your answer is 27x^6/16.
Given:
Brown’s time for running a mile in gym class = 9.9 minutes
Ray’s time for running a mile in gym class = 9.47 minutes
Malcolm’s time for running a mile in gym class = 9.76 minutes
To find:
Who ran the mile in less time?
Solution:
It is given that the time taken by Brown, Ray and Malcolm to cover a mile are 9.9 minutes, 9.47 minutes and 9.76 minutes respectively.
9.47 < 9.76 < 9.9
Since, 9.47 minutes is the lowest time, therefore Ray can run a mile in less time.
Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3

Sort of explanation:
This is a 30° 60° 90° triangle, so the rules below apply:
x is the short leg of the triangle, located across from the 30° angle. (In this problem, the short leg is labled b)
The hypotenuse leg is across from the right angle, and is always 2x (In this problem, the hypotenuse leg is labled c)
The long leg of the triangle is located across the 60° angle and is always x√3. (in this problem, the long leg is labeled a)
