Step-by-step explanation:
3,10,5 CANNOT be a triangle as 3+5 IS NOT greater than or equal to 10
10,8,5 CAN be a triangle as 8+5 is greater than or equal to 10
a simple way to figure out if three lengths can be a triangle is to take the two smaller numbers and see if they are greater than or equal to the larger number.
15 dimes at 15x10=$1.50
12 nickels at 12x5=$0.60
$1.50+0.60=$2.10
So Alexandra has 15 dimes and 12 nickels
