Three watches and five lamps cost $176 in all. Five watches and three lamps cost $208 in all. What is the cost of one lamp?
$200/5 lamps= $40 per lamp
Final answer: $40
Using the elimination principle, the cost of one lamp is $16
Let :
watches = a Lamps = b3a + 5b = 176 - - - - (1)
5a + 3b = 208 - - - (2)
Multiply (1) by 5 and (2) by 3
15a + 25b = 880 - - - - (3)
15a + 9b = 624 - - - - - (4)
Subtract (3) and (4)
16b = 256
b = (256 ÷ 16)
b = $16
Therefore, the cost of one lamp is $16

(16.5+1.5n)°(12+2n)°
Answer:
1.7n +28.5
Step-by-step explanation:
you compare like terms first
1.5n add it to 2n
it will equal to 1.7
then add 16.5 to 12
it will equal to 28.5
Your new equation will be
1.7n+ 28.5 if it was equal to something let's say it was equal to 180 as an example:
your equation will be
1.7n + 28.5= 180
-28.5= -28.5
1.7n= 151.5 you would divide it
it would equal 89.1 and change.
Which equation is represented by the graph below?
Answer:
B.
Step-by-step explanation:
The lines positioning shows a negative slope already, so it cant be C or D
Slope is a rise over run basis. You can check this just from points alone, the line would be much steeper if the slope was -2.
Hope this helps!
