Let's translate your words into numbers and fractions. So it's
5/4 - 1/x - 2 = -4/-4.
Let's Simplify it first by eliminating -4/-4, the answer will be 1 since negative divided by negative is positive and 4 divided by 4 is 1.
5/4 - 1/x - 2 = 1
Then Get the GCF of the equation which is 4x.
Then divide the whole equation by 4x and it would be,
<span><u>5/4 - 1/x - 2 = 1
</u></span> 4x
Then it will look like this, 5x-8x-4 = 4x
Then transpose, 5x - 8x - 4x = 4
Simplify by deducting the left side. -7x = 4
Then divide both sides by -7.
Then the final answer would be x = -4/7
Answer:
3 ^ 9/5
Step-by-step explanation:

Congruent means they are the same length.
Set both lines equal to each other and solve for x:
x + 5 = 2x -10
Subtract x from both sides:
5 = x -10
Add 10 to both sides:
x = 15
Now you have a value for x, replace x in the equation of the line and solve:
QR = x +5 = 15 +5 = 20
Answer:
57.62% of players weigh between 180 and 220 pounds
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
What percent of players weigh between 180 and 220 pounds
We have to find the pvalue of Z when X = 220 subtracted by the pvalue of Z when X = 180.
X = 220
has a pvalue of 0.7881
X = 180
has a pvalue of 0.2119
0.7881 - 0.2119 = 0.5762
57.62% of players weigh between 180 and 220 pounds
