Multiply the second question by -1 to cancel out the y’s. then add them. 11x=-11
x=-1
substitute that back into one of the equations
-3(-1)+y=-5
3+y=-5
y=-8
The third piece is 59 cm long.
Add the first two pieces up. 7+34= 41. Since the whole stick is 100 cm long, subtract 41 from 100 to find the length of the third piece. 100-41=59.
512.
8 multiplied by 8 multiplied by 8 is 512
