katovenus [111]

2x = 31 - 5y \\ x =  \frac{31}{2} -  \frac{5}{2}y

6x = 13 + y \\ x =  \frac{13}{6}  +  \frac{1}{6} y

6th grade math help me please !
antiseptic1488 [7]

First we have to figure out how much 3 bags cost using the total cost of $8.25

That means. we would do 8.25/3 and 8.25 divide by 3 equals 2.75.

Now we know that each bag costs approximately $2.75

All we have to do now is multiply 2.75 by 4 to get the cost for the total of 4  bags.

4 times 2.75 is exactly 11 dollars, if might change if theres tax.

But, the answer would be 4 bags costs $11.
