Answer:
y = 6.8
Step-by-step explanation:
Area of kite = 1/2 xy
51.68 = 1/2 (15.2) y
2(51.68)/15.2 = y
y = 6.8
Answer:
n = 1/2
Step-by-step explanation:
So the equation is 4/5n - 1/5 = 2/5n.
So, the first thing that we need to do is get the variable on one side.
So, to do that we need to subtract 4/5n on both sides.
Now our equation is -1/5 = -2/5n
Now the last step is to simplify.
To do that, we need to multiply by the reciprocal of 2/5 on both sides.
That leaves us with 1/2 = n
31 in total and the smaller one has 13. So just subtract 31-13 and it means there are 18 balls in the larger bag
