Answer:
$8.75
Step-by-step explanation:
Create a proportion where x is the cost for 7 bags:
= 
Cross multiply and solve for x:
4x = 35
x = 8.75
So, the cost of 7 bags is $8.75
4 to 7......add them = 11
4/11 * 33 = 132/11 = 12
7/11 * 33 = 231/11 = 21
Answer:
(-2,1) and (3, -4)
Step-by-step explanation:
(-2,1) and (3, -4) this is where the lines intersect, hence these are the solution. :) have a great night!
By add two to the equation two
y=4
by solving two with the volume of y
3x+8=2 , 3x=-6 , x=-2
so the answer is a ( -2 ,4)
