They sold 76 t-shirts and 24 warm up pants.
Step-by-step explanation:
Cost of one t-shirt = $20
Cost of warm up pants = $45
Total sold = 100
Worth of sold items = $2600
Let,
x be the number of t-shirts.
y be the number of warm up pants.
According to statement;
x+y=100 Eqn 1
20x+45y=2600 Eqn 2
Multiplying Eqn 1 by 20
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 25
Putting y=24 in Eqn 1
They sold 76 t-shirts and 24 warm up pants.

It's just a mathematical constant you can come across in trigonometry, geometry, sequence like Fibonacci and others. You may find it in fractals also and in many shapes in the nature but not necessarily always true.
It might be a coincidence in some natural shapes, but definitely it is a recognized math contant useful in many math domains
I'm positive its D but I'm for sure it is not B
Hello!
If this square pyramid originally had a volume of 180 in³, and it is multiplied by ten, we add a zero and get 1800 in³.
I hope this helps!
5x+13y=-13
13y=-5x-13
y=-5/13x-1
Y-intercept = -1
Slope = 5/13
