Answer:
3: 2q − 4 = 20
Step-by-step explanation:
Solve for q:
2 q - 4 = 20
Add 4 to both sides:
2 q + (4 - 4) = 4 + 20
4 - 4 = 0:
2 q = 20 + 4
20 + 4 = 24:
2 q = 24
Divide both sides of 2 q = 24 by 2:
(2 q)/2 = 24/2
2/2 = 1:
q = 24/2
The gcd of 24 and 2 is 2, so 24/2 = (2×12)/(2×1) = 2/2×12 = 12:
Answer: q = 12
The answer is C because for algebraic expression you need a coefficient, variable and a constant
Answer:
Step-by-step explanation:
the y= equation shows how... b/c we can just plug y into the 2nd equation and eliminate y and have one variable, x , to solve for :)
Answer:


Step-by-step explanation:
Let's rewrite the equation as:

Now, let's find its derivate:

Let's evaluate x=0.27 and x=2:


Keep in mind that when we derivate A(average speed) we find the average acceleration, thats why the result is given in mi/h^2, also it explains the minus sign, because for every stop you make on the trip you are decelerating.
