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:
x=7
Step-by-step explanation:
AB=BC[ because two sides of isosceles triangles are equal ]
or, 2x+9=5x-12
or,9+12=5x-2x
or,21=3x
or,x= 21/3
therefore, x=3
The amount after 3 years would be $221.74
<u>Explanation:</u>
Given:
Principal, P = $200
Rate of interest, r = 3.5%
Time, t = 3 years
Amount, A = ?
We know:
Substituting the value we get:
Therefore, the amount after 3 years would be $221.74
Slope: (y2-y1)/(x2-x1)
(-11-1)/(6-(-3)) = -12/9 = -4/3
The slope is -4/3
To find the median, add up the frequency column to find how many trains there were in total. There were 44 trains in total in this grouped frequency table, so work out 44 + 1 2 = 45 2 = 22.5. The median is therefore between the 22nd and 23rd values.
