If x^2 -7x=30 and x>0, what is the value of x-5
laila [671]

Answer:

5

Step-by-step explanation:

x^2-7x=30

x^2-7x-30=0

a = 1, b = -7, c = -30

sqrt(b^2-4ac)

sqrt(49+120)

sqrt(169)

13

-b +/- 13

7 + 13 = 20

7 - 13 = -6

2a = 2

20/2 = 10

-6/2 = -3

we know x>0, so it cant be -3. so now its just 10 - 5

Jerome found another feather that made the difference between the longest and shortest feather 1 3/4 inches what could be the le
Alchen [17]

Answer:

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

Step-by-step explanation:

A mathematical translation of the statement of the problem is:

x - y = \frac{7}{4}

Where x, y represent the lengths of the longest and shortest feathers, respectively. Let assume that length of the shortest feather is 1/4 inches. Then, the length of the longest feather is:

x = y + \frac{7}{4}

x = 2

By assuming that shortest feather has a length of 1/4 inches, the length of the longest feather is 2 inches.

Mand N are two events P(M) = 0,60, P(N) = 0.20, and P (M and N) = 0.1.
Rzqust [24]

Answer:

0.7

Step-by-step explanation:

This can be easily solved if we know the formula:

P(A or B) = P(A) + P(B) - P(A and B)

So, for this problem, we can modify the formula to be:

P(M or N) = P(M) + P(N) - P(M and N)

Using given information, we can solve:

P(M or N) = P(M) + P(N) - P(M and N)

P(M or N) = 0.6 + 0.2 - 0.1

P(M or N) = 0.7

Last answer choice is right, 0.7
