Answer: r = 7
Step-by-step explanation:
Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation.
Answer:
The percentage change from July to November is 67.27 %
Step-by-step explanation:
Given as :
The number of tourists at the beach per weekend in the month of July =
= 55,000
The number of tourists at the beach per weekend in the month of November =
= 18,000
Let the percentage change from July to November = A %
Or, % decrease change =
× 100
So , A % =
- \textrm
}{\textrm
}[/tex] × 100
or, A % =
× 100
Or, A % =
× 100
Or, A = 67.27 %
So percentage change between two months = 67.27 %
Hence The percentage change from July to November is 67.27 % Answer
Answer:
denominators are zero for x=1
there is no solution
Step-by-step explanation:
We suspect your equation is supposed to be ...
10/(5x -5) +1/5 = 2/(x -1) . . . . . parentheses are required on denominators
The denominators will be zero for x=1.
This version of the equation has no solution. It simplifies to ...
2/(x-1) + 1/5 = 2/(x -1)
1/5 = 0 . . . . . subtract 2/(x-1) from both sides
There is no value of x that will make this equation true.
_____
<em>Alternative interpretation</em>
The way your equation is written, it must be interpreted according to the order of operations to be ...
(10/5)x -5 +1/5 = (2/x) -1 . . . . x=0 makes the denominator zero
2x -3.8 = 2/x
2x^2 -3.8x = 2 . . . . multiply by x
2(x^2 -1.9x +.95^2) = 2 +2(0.95^2)
(x -0.95)^2 = 1.9025
x = 0.95 ± √1.9025 ≈ {-0.4293, 2.3293}
