Step-by-step explanation:
Answer:
5/9
Step-by-step explanation:
Let the denominator be x and numerator be y.
Given, numerator is 4 less than denominator
=> y = x - 4 ...(1)
When 5 is added to both:
Numerator = y + 5 , and, denominator = x + 5
Now their ratio is 5/7.
=> (y + 5)/(x + 5) = 5/7
=> 7(y + 5) = 5(x + 5)
=> 7y + 35 = 5x + 25
=> 7y - 5x = 25 - 35
=> 7(x - 4) - 5x = -10 {y=x-4}
=> 7x - 28 - 5x = -10
=> 2x = 18
=> x = 9
Thus,
Fraction is y/x = (x-4)/x = (9-4)/9 = 5/9
Given:
The equation is

To find:
The solution of the given equation.
Solution:
We have,

It can be written as


Multiply both sides by 7.




Divide both sides by 7.


Therefore, the value of z is -2.
Statement 3: tri egc = tri egb
statement 4: tri ebc is equilateral.
reason 5: equilateral triangles have equal angles
Answer:
Lines are described as connecting curve joining two points.
Step-by-step explanation:
In coordinate geometry, graph theory, we have points which do not occupy any space.
Any two points can be connected by a curve or a straight line. If two points are joined by a straight line, then we have the slope of the line i.e. the tangent of angle of the line with x axis is constant.
Straight lines would be of the form ax+by+c=0
Hence in equation form, lines would have equations in linear form of both x and y.
Lines have constant slope throughout the region.
Lines can be extended from -infinity to +infinity
Any two distinct points can make a line, but 3 points need not lie on the same line.
