Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)
0.71 r decimal form and 71/100r and just simplified.
Answer:
The cost written as a fraction is --> 4 13/99
Step-by-step explanation:
Let x = 4.131313
100x = 413.1313
So, 100x - x = 99x
100(4.131313) - 4.131313 = 408.99, or 409 when rounded
x = 409/99
x = 4 13/99
