49+1=50
7x7=49
7 divided by 7 equals 1
The solution's something you can really easily pick up, I promise.
The solution is simply the point where the two lines connect.
In this case, it's (2,5). (x,y)
Hope this helped!

Answer:
Xena earns $144 per a week.
Step-by-step explanation:
Harry earns - $ h
Xena earns - $ x
George earns -$ g
Harry earns $45 a week more than Xena. h= x+45
George earns $18 a week less than Xena. g = x - 18
If Harry earns the same amount in two weeks that George earns in three weeks
2h = 3g
So, we have the system of 3 equations:
h= x+45
g = x - 18
2h = 3g (*)
Substitute values of h and g into equation (*)
2(x+45) = 3(x-18)
2x + 90 = 3x - 54
90+54 = 3x- 2x
x= 144
If an items weight is 0 it would be like a peice of paper or cotten ball. when a cotten ball is weighed it does not affect anything. as when a peice of paper is wieghed it moves its meater 1 inch.
R would equal -189, there is step by step in the picture
