Can someone help me please?
I don't really understand it ​

T-shirts= $7.5 and Shorts=$10

Step-by-step explanation:

T-shirts = X

shorts = Y

3x + 2y =42.5

5x + 3y = 67.5

use addition method

5 (3x + 2y = 42.5)

-3 (5x + 3y = 67.5)

15x + 10 y = 212.5

-15x -9y = 202.5. then..

15x - 15x= 0

10y - 9y = y

212.5 - 202.5 = 10 therefore y=10

substitute y into any equation

3x + 2(10)= 42.5

3x +20 = 42.5

3x= 42.5-20

x= 22.5/3

x=7.5

so T= $7.5 and S= $10

pi x^2

step-by-step explanation:

pi times x squared

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
