8x+(4*30)=6(6+30)
8x+120=6x+180
2x=60
x=30 pounds of coffee
4 months because, 2 divided by 0.5 is 4 therefore she has been measuring the tree for 4 months
Answer:
sorry im not sure about the answer but this is how you figure it out
Step-by-step explanation:
50a+30b=550
after you simplify = 5a+3b=55
44a+36b=532
after you simplify=11a+9b=133
then you try to find a number
5a+3b=55
then you have to find different possibilities of a and b and if it can fit into both equations then it is correct
