Xy=k, whenever the product of two variables is a constant it is called inverse variation. This is an inverse relationship, intuitively because, as the value of one variable increases, the other decreases and vice versa.
It is easy to spot as xy=k or y=k/x.
Equation: <span>5/7d=2/3
Work:
5d/7 = 2/3
5d = 2/3 x 7
5d = 14/3
d = 14/3/5
d = 14 / 3 x 5
d = 14/15
Final Answer:
14/15 or 0.933333

Answer:
67°F
Step-by-step explanation:
The mean is another way to say average.
To find the average: you have to add up all of the temperatures, then divide by how many numbers (in this case, time slots) are there.
58°F + 60°F + 61°F + 67°F + 69°F + 73°F + 74°F + 74°F = 536°F
536°F ÷ 8 (total number of time slots) = 67°F
Answer:
b)Add the equations to eliminate x.
Step-by-step explanation:
y= x+20
y= - x+2
Result of the addition: (-x cancels x)
2y = 22
y =11
11=x +20 -9 = x
11=9+2
11 = -9 +20
