So first we need to get rid of that naughty sales tax so we need to divide 30.45 by 1.05 since 30.45 is 105% of the pre-tax price. We get the answer of 29 and subtract 12 from 29 since the long fleece socks cost 12 bucks and we get 17 dollars. Since there are 2 pairs of regular songs we divide 17 by 2 and get 8.5
So the regular socks cost $8.50
Checking work 8.5*2=17
12+17=29
1.05*29=30.45

Answer: 60 mph.
(486+316+638)/24
The distances given by the table. The time driven is 24 (given by the problem). So the average speed is simply the total distance divided by the time driven.
Step-by-step explanation:
Answer:
x= 4/5 or x = -2
Step-by-step explanation:
Step 1: Subtract -6x from both sides.
5x^2 -8 - -6x = -6x -6x
5x^2 + 6x - 8 = 0
Step 2: Factor left side of equation.
(5x - 4) (x + 2) = 0
Step 3: Set factors equal to 0.
5x - 4 = 0 or x + 2 = 0
Hense the Answer is x= 4/5 or x = -2
Answer:A C B B
Step-by-step explanation: i had did this before
To find the inverse of a function, replace all the x's with y's and all the y's with x's.
y= -3v(x+7) + 10
x= -3v(y+7) + 10
Now that we have a new function, we solve for y.
x-10= -3v(y+7)
-x-10=3v(y+7)
(-x-10)^3=y+7
y=(-x-10)^3 - 7
Now we have the inverse function.
