Call T the price of the T-shirts and P de price of the jeans
Initially (without discount)
2T + P = 40
One month later (half prices)
2 (T/2) + 5(P/2) = 60
T +5P/2 = 60
To solve the system of equations multiply the second equation by 2 and substract it from the first equation
2 T + 5P = 120
- (2 T + P = 40 )
________________
4P = 80
P = 80/4
P = 20
From 2T + P = 40
T = (40 - P) / 2 = (40 -20) / 2 = 20/2 = 10.
The price of a T-shirt is $10 and the price of a pair of jeans is $20.

Step-by-step explanation: i would right an explanation but i cant put it all so you will just have to trust me
Answer:
Area = Length × width
16 = (3x +2 ) × ( x)
16 = 3x² +2x
3x² +2x -16=0
( 3x+8 ) ( x -2 ) =0
3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6
x-2=0 —> x = 2
I hope I helped you^_^
When we talk about free form shapes, it can be curve, lines or simple concave or convex polygons.
1. The shape can be closed or open.
2. The curve can cross each other, that is lines or doodled lines may intersect.
3. The free form shape consist of either lines or doodled lines, which we call an open curve.
When we talk about Geometric Shapes, it consist only of Polygons, which consist of triangles, Quadrilaterals, polygons.
1. The curve is simple closed curve.
2. It consist entirely of line segments.
3. The intersection within the curve is a point.
