Answer:
An unknown variable
Step-by-step explanation:
r is an unknown variable -> the equation is used to solve for it.
Answer:
8
Step-by-step explanation:
If we assume the '17' is the hypotenuse ( the Q does not say)
then 15^2 + x^2 = 17^2 via the pythag theorem for right triangles
x = 8
654 over 3 = divide the both 654 and 3 by 3.
It will give you 218 over 1.
So the answer is 218.
-3 (x - 5) - 8 (y + 2) + (-3) (6 - 4b)
First, simplify your brackets. / Your problem should look like: -3 (x - 5) - 8 (y + 2) + -3 (6 - 4b)
Second, simplify. / Your problem should look like: -3 (x - 5) - 8 (y + 2) - 3 (b - 4b)
Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19
Answer: -3x - 8y + 12b - 19 (D)
