The x is 2 :) I hope it’s right! I’m pretty sure it is though !
the total number of out comes would be 16^2 or 256.
some extra things...
A numbered card from 1 - 10 would be 1 over 10 or 10% chance of picking correctly.
a number cube from 1 - 6 would be 1 over 6 or 16.66% chance of picking correctly.
if you want to combine these and pick one from both, it becomes 1 over 16 or 6.25% chance of picking both correctly.
The slope of -5x + y = 56 is 5
the slope of x + y = -4 is -1
Perimeter (P) of a square = 4s ; where s is the length of a side
1 yd = 4s
yd = s
Area (A) of a square = s²
= (
)²
Now, convert from yard to foot to inch:
(
)² x (
)² x (
)²
= (3 x 3 x 12 x 12) ÷ (4 x 4)
= 81 in²
