Answer: Assuming that event A has occurred
Step-by-step explanation:
We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.
Answer:
x=5/3 hope i helped you
Step-by-step explanation:
Since, in this case, we have 4 options then you just need to substitute each number.
A. y = 5/x
B. y = 14/x
C. y = 9/x
D. y = 3.5x
We know that x= 2 when y=7. So...
A. y = 5/x
7=5/2
7=2.5
This is false.
B. y = 14/x
7= 14/2
7=7
This is right, So True.
C. y = 9/x
7=9/2
7=4.5
False
D. y = 3.5x 7=3.5(2)
7=7
This one is also true.
In this case we look for definition.
he statement " <span>y </span>varies inversely as <span>x </span>means that when <span>x </span>increases, <span>y </span>decreases by the same factor. In other words, the expression <span>xy </span>is constant:
xy = k
where k is the constant of variation.
We can also express the relationship between x and y as:
y = k/x
where k is the constant of variation.
