Mira picked two numbers from a bowl. the difference of the two numbers was 4, and the sum of one-half of each number
was 18. the system that represents mira's numbers is below.
x - y = 4
3x + y = 18
which two numbers did mira pick?

multiply  1/2x - 1/2 y = 4 by 2,,  we get x - y = 8

x   - y =   8   and  

x  + y = 18                  Adding these 2 equations:-

2x = 26  

x = 13

and y =  18-13 = 5

Mira picked the numbers 13 and 5.

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
