Answer:
Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
The value of 'x' is 10°
<h3>How to determine the angles</h3>
We have that supplementary angles sum up to 180
M∠A = (6x +4)° and m∠B = (10x + 16)°.
Then,
6x + 4 + 10x + 16 = 180
Collect like terms
16x + 20 = 180
16x = 180 - 20
16x = 160
x = 160/ 16
x = 10°
Thus, the value of 'x' is 10°
