Answer:
3+(k+1)1.5= 3
Step-by-step explanation: you do 1.5 * k and 1 and get 1.5k + 1.5
then you go 3 +1.5k+1.5=?
1.5k+4.5=?
-1.5k -1.5k
4.5=-1.5
_ . _
-1.5 . -1.5
k=3

Answer:
x = 4
y =23
work:
plug in the value of Y to -2x-3y=-2. -2x - 3(<span>6x-1) = -2
multiply 3 and the numbers in parenthesis. -2x -18x - 3 =-2
combine like terms (-2x -18x). -20x - 3 = -2
subtract 3 from both sides to isolate the variable. -20x = -5
divide to isolate the variable (-20/-5) x = 4
-
now that we know the value of x, it'll be easy to find Y.
Plug it in to the first equation.
</span><span>y=6(4)-1
</span>y = 24 - 1
y = 23
so x = 4
and y = 23

Answer:
Step-by-step explanation:
Remark
The wholesale price of the shoes is 125 dollars
The retailer marks it uu to 35% more to the wholesale price.
So the price is now 125 + 35% * 125 dollars
That amount is 125 + 35/100 * 125 = 125 + 43.75 = 168.75
The government wants its cut of 6.5% of the selling price
So the final price is 168.75 + 168.75 * 6.5/100
The final price is 168.75 + 10.97 = 179.72
Answer: A customer pays 179.72 dollars.
