I would have to go with the first one because 2(3x-5)=1 is the same as 6x-10=1
then all you have to do is divide 11 by 6 and the answetr should be c or in this case x=1.83
to check your work do this 6(1.83)-10 and your answer should come to .98
all you have to do is round to 1.0

Let
x ------> number of switch type A
y -----> number of switch type B
so
Remember that
1 hour=60 min
32 hours=32*60=1,920 minutes
4x+5y=1,920 -------> equation 1
3x+5y=1,740 ------> equation 2
Solve the system of equations
Solve by graphing
using a graphing tool
see the attached figure
Solution is
x=180
y=240
therefore
<h2>the number of switch type A was 180</h2><h2>the number of switch type B was 240</h2>
Answer:
The second term defines the value that will be depreciated by the rate of 22 units for m months.
Step-by-step explanation:
Given is :
The value of the gadget after 'm' months = 2020 - 22m
This expression tells us that, each month Meghan's gadget's price falls by 22 units from the original value.
The original value of the gadget is 2020 units.
Therefore, the constant term (2020 )of the expression represents the original value of the gadget,
And the second term defines the value that will be depreciated by the rate of 22 units for m months. And m defines the number of months Meghan will keep the gadget.
X=14 because it is half of 28
Hope this helps
