Answer:
27x-6
Step-by-step explanation:
To distribute 6(3x-1) properly, 6 needs to be multiplied with 3x and -1.
6*(-1)=-6,
3x*6=18x.
Without simplifying, the answer we get from this is 18x+9x-6. 18x+9x=27x, so the algebraic expression equivalent to 6(3x-1)+9x is 27x-6.
Answer:
y = 3.99 + 0.5x
Step-by-step explanation:
y = 3.99 + 0.5x
y = total cost
x = amount of toppings
An inertial reference frame is a frame of reference in which a body remains at rest OR moves with a constant LINEAR velocity. Answer choices A, C, and D are moving linearly at a constant rate and are all inertial frames of reference. Answer choice E is motionless, and is therefor an inertial frame of reference. Answer choice B is rotating at a constant rate. Rotation is not an inertial frame of reference.
Therefor, the answer is B.
We divide by 2 on both sides.
We get the final answer as
x = 5/2 = 2.5
