Answer:
177
Step-by-step explanation:
Adults: 11 x $8 = 88
Children: 17 x $4 = 68
Pensioners: 3 x $7 = 21
88 + 68 + 21 = 177
3x^2y^3+5x^3y^3-6+x^3y^2-2
= (3x^2y^3+5x^3y^3+x^3y^2)-(6+2)
= x^2y^2(3y+5xy+x)-8.
The final answer is x^2y^2(3y+5xy+x)-8~
X = 4
Use division divide both sides by 3
3x/3 leaves x
12/3=4
Hope it helps
x=4
