Answer:
I think she is incorrect she need to change all the fractions to the same denominators
Step-by-step explanation:
We are going to change all the fractions to 64
9/64 stays the same
5/32 multiply 2 then 10/64
1/16 multiply by 4 then 4/64
1/8 multiply by 8 then 8/64
Now we can order then
5/32 > 9/64 > 1/8 > 1/16 This is the right order
She was wrong.
Let n represent a number
then, n+2 represents the next even number
n + (n+2) = 94
(basically multiplying (n+2) by + 1)
n + n+ 2
2n+2= 94
2n +2 -2 = 94 -2
2n = 92
n = 46
therefore,
n+ 2
= 46+ 2
= 48
Check:
48 + 46 = 84

Answer:
Step-by-step explanation:
xy = k
where k is the constant of variation.
We can also express the relationship between x and y as:
y =
where k is the constant of variation.
Since k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5(2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = .
Example 1: If y varies inversely as x, and y = 6 when x = , write an equation describing this inverse variation.
k = (6) = 8
xy = 8 or y =
Example 2: If y varies inversely as x, and the constant of variation is k = , what is y when x = 10?
xy =
10y =
y = × = × =
k is constant. Thus, given any two points (x1, y1) and (x2, y2) which satisfy the inverse variation, x1y1 = k and x2y2 = k. Consequently, x1y1 = x2y2 for any two points that satisfy the inverse variation.
Example 3: If y varies inversely as x, and y = 10 when x = 6, then what is y when x = 15?
x1y1 = x2y2
6(10) = 15y
60 = 15y
y = 4
Thus, when x = 6, y = 4.
2nd answer choice
constant of variation is xy. XY=23. If X=7 then Y=23/7.
