Ray QM is the angle bisector of angle NQR. If angle PQN = 7x + 15 and angle NQM = 4x, what is the value of x?
1 answer:
Answer:
x = 2.7
Step-by-step explanation:
From the question given above, the following data were obtained:
QM = angle bisector of angle PQR
Angle PQN = 7x + 15
Angle NQM = 4x
x =?
Since QM is the angular bisector, it means that it bisect PQR into two equal angle i.e 45° each.
See attachment for diagram.
Thus, we can obtain the value of x as follow:
7x + 15 + 4x + 45= 90° (angle in a right angle triangle)
7x + 4x + 15 + 45= 90
11x + 60 = 90
Collect like terms
11x = 90 – 60
11x = 30
Divide both side by 11
x = 30/11
x = 2.7
Therefore, the value of x is 2.7

Answer:
Hence the pricing for each product will be taronges with 2 euros and mandarins with 2.5 euros.
Step-by-step explanation:
Given:
2 kg of taronges and 3 kg mandarins cost 11.5 euros
3kg taronges and 2 kg mandarins cost 11 euros
To Find:
Price for each product
Solution:
<em>Consider </em>
<em>Taronges =x euros</em>
<em>Mandarins=y euros</em>
So by given condition,
....................equation(1)
and ...........equation (2)
So , using substitution method,
.......equation (3)
Using above value in equation(1) we get ,
)
y=2.5 euros
Using above value in equation(3) we get ,
x=2 euros
