Hello!
*I'm not very good at algebra, so I am not 100% sure this is correct!*
w = cost of washer
d = cost of dryer
w + d = $586
w = d - 64
d - 64 + d = 586
2d = 586 + 64
2d = 650
d = 650 / 2 = 325
586 - 325 = 261
Check 325 - 261 = 64
So, the dryer costs $325 and because the washer is $64 less than the dryer, it costs $261.
Answer:
1 cm: 200 cm (if they don't give units) (most likely this answer) (1:200)
if the units are centimeter and meter though, then it's
1:2
Step-by-step explanation:
there are 100 cm in 1 meter, so 1cm:2m
is actually 1cm : 200cm
The equation 5/2 - x + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0 is a quadratic equation
The value of x is 8 or 1
<h3>How to determine the value of x?</h3>
The equation is given as:
5/2 - x + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0
Rewrite as:
-5/x - 2 + x - 5/x + 2 + 3x + 8/x^2 - 4 = 0
Take the LCM
[-5(x + 2) + (x -5)(x- 2)]\[x^2 - 4 + [3x + 8]/[x^2 - 4] = 0
Expand
[-5x - 10 + x^2 - 7x + 10]/[x^2 - 4] + [3x + 8]/[x^2 - 4] = 0
Evaluate the like terms
[x^2 - 12x]/[x^2 - 4] + [3x + 8]/[x^2 - 4 = 0
Multiply through by x^2 - 4
x^2 - 12x+ 3x + 8 = 0
Evaluate the like terms
x^2 -9x + 8 = 0
Expand
x^2 -x - 8x + 8 = 0
Factorize
x(x -1) - 8(x - 1) = 0
Factor out x - 1
(x -8)(x - 1) = 0
Solve for x
x = 8 or x = 1
Hence, the value of x is 8 or 1

Answer:
$2.50
Step-by-step explanation:
Since there are 2 pounds in the bag, you simply divide $5.00 by 2 to get the price of a single pound.
33,000% should be the answer
