Answer:
21 cards left to be signed
Step-by-step explanation:
1/3 of 72 is 24
So Harrison signed 24
3/8 of 72 is 27
Sp Alwine signed 27
24+27=51
So 72-51=21
21 cards left to be signed
The total will be 57.23. Because tax would be 4.24 and add it to 52.99 and you get 57.23.
Answer: X = 5
Step-by-step explanation:
The correct formula to solve the problem is:
11x - 8 = 47
First, add 8 to each side.
11x = 55
Solve it by dividing both sides by 11:
X = 5

Answer:</h3>
x = 1
<h3>
Step-by-step explanation:</h3>
<em>The only solution is an extraneous solution</em>, which is to say the equation has no solution.
The rational expression reduces to -1 (for x≠1), which makes the equation ...
1 = 1/x
The only solution to this is x=1, which is specifically disallowed.
___
If you subtract the right side, the equation becomes ...
((-x+1)(x) +2(x)(x -1) -(x -1))/(x -1) = 0
(-x^2 +x +2x^2 -2x -x +1)/(x -1) = 0 . . . . eliminate parentheses in the numerator
(x^2 -2x +1)/(x -1) = 0 . . . . . . . . . . . . . . . collect terms
(x -1)^2/(x -1) = 0 . . . . . . . . . . . . . . . . . . . factor
This is undefined for the only value of x that could possibly be a solution, x=1.
