6y-4=4y+2
2y=6, so y=3.
Plugging it in, you get that AC equals 4*3+2=14.
This is an isosceles triangle.
No, Carlos doesn't have enough money. This is because he only has seven dollars to spend and his total would be $8.25. He wants to buy two granola bars which equal $5. Then you add $2.50 and the total would be $7.50. Then you add the pack of gum and the total could come out to $8.25.
