Making 1 necklace takes her 0.5 hours, so making x necklaces, will take her 0.5x hours.
Making 1 bracelet takes her 1 hour, so making y bracelets, will take her 1*y=y hours.
So in total, she needs to work for 0.5x + y hours.
Since she has fewer than 20 hours, 0.5x + y must be smaller that 20.
Thus, we have 0.5x + y<20
Answer:0.5x + y<20

Answer:
<h2> 7 months</h2>
Step-by-step explanation:
Step one:
given data
the cost of the laptop= $800
initial payment= $200
monthly payment = $60
let the number of months be x
the expression for the situation is the function for the equation of line
y=mx+c
Step two:
the expression for the situation is
800=200+60x
solve for x
800-200=60x
400=60x
divide both sides by 60
x=400/60
x=6.7
Approximately 7 months

Answer: In a regular decagon, there are 10 lines of symmetry.
Step-by-step explanation:
Line of symmetry divides a figure into two equal halves so that if you flip the half image over the line of symmetry , the figure will look unchanged.
A regular decagon has 10 vertices and 10 edges.
To draw line of symmetry :
1.Draw lines to meet the exactly opposite point [shown by red color in the picture attached with the answer].
∴ 10 vertices will form 5 lines of symmetry.
2.Draw lines from the mid points of all the edges to the midpoint of the exactly opposite edge [shown by blue color in the picture attached with the answer].
∴ 10 edges will form 5 lines of symmetry.
⇒Total lines of symmetry in a decagon =5+5= 10
