When six times a number is decreased by five, the result is 49. what is the number?

solong [7]

Put this into an equation. Make the missing value "x".
6x - 5 = 49
49 + 5 = 54
54 / 6 = 9
x = 9.
The missing number is 9.

Hope This Helps You!
Good Luck Studying :)

Answer:

7.3

Step-by-step explanation:

For this question, you must use the distance formula. The distance formula is based around Pythagorean Theorem, so you will see some similarities.

Distance = $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}$

X2 is 7 (X coordinate of school)

X1 is 5 (X coordinate of friend's house)

7 - 5 = 2

2^2 = 4

Y2 is 7 (Y coordinate of school)

Y1 is 0 (Y coordinate of friend's house)

7 - 0 = 7

7^2 = 49

4 + 49 = 53

$\sqrt{53}$ = 7.2801...

Round to the nearest tenth...

Answer:

see below

Step-by-step explanation:

1. 0 = (r + 1)(r + 8)

Using Zero Product Property, r = -1, r = -8

2. h(r) = (r + 1)(r + 8)

= r² + 9r + 8

= (r + 9/2)² - 81/4 + 8

= (r + 4.5)² - 12.25 (Complete the square)

Vertex: (-4.5, -12.25)
