What is the solution of this system of linear equations?<br><br> 3y = x + 6<br><br> y – x = 3
Naya [18.7K]
<span>3y = x + 6
y – x = 3 ----------->  x=y - 3 (substitute in 1st equation)

3y = y - 3 +6
3y - y = 3
2y = 3
y = 2/3

x= y - 3 = 2/3 -3 = 2/3 - 9/3 =  - 7/3

</span>x= - 7/3, y = 2/3<span>

Chris wants to paint the ceiling of his restaurant. The ceiling is in the shape of a square. Its side lengths are 55 feet. Suppo
d1i1m1o1n [39]

Answer:

11 cans

Step-by-step explanation:

Since you know that the ceiling is in the shape of a square and each side is 55ft, you can multiply 55x55 to get 3075, which is divided by 275 due to the amount of paint in a can. It would result in 11 cans, but if it were a decimal like 11.3, then you would need 12 cans since you can't split a can.
