Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10

The volume of a 3d rectangular prism is the length*width*height
Therefore your answer is:
3.5*8*0.5 = 14
Amount of purchase that Steve made = $40
Percentage of tax that Steve needs to pay = 10%
Then
Amount of tax that Steve needs to pay for the purchase = (10/100) * 40
= 1 * 4 dollars
= 4 dollars
Then
The total amount including tax
that Steve needs to pay for the purchase = (40 + 4) dollars
= 44 dollars
So the dollar amount of tax that Steve had to pay is $4 and
the total amount that Steve had to pay was $44.
