Step-by-step explanation:



Answer:
x=18 y=2.5
Step-by-step explanation:
Step 1- 11x+10=9x-26
-9x -9x
Step 2- 2x+10=-26
-10 -10
Step 3- 2x/2=36/2
Conclusion- x=16
Step 1- 7y+5=9y
-7y -7y
Step 2- 5/2=2y/2
Conclusion- y=2.5
8 x 5 x 5 = 200cm^3
8 x 8 x 1 = 64 cm^3
200 + 64 = 264cm^3
Answer:
L = 
Step-by-step explanation:
