Answer: n = -9

Step-by-step explanation:

-6n + 5 = 59 (Given)

-6n -5 = 59 - 5 (Subtraction Property of Equality)

-6n = 54 (Simplify)

\frac{-6}{-6} = \frac{54}{-6} (Division Property of Equality)

n = -9 (Simplify)

Solve 10 X + 8 / 2 X + 7 is equal to 4 ​
ale4655 [162]

Answer:

x = 10

Step-by-step explanation:

\frac{10x + 8}{2x + 7}  = 4

or, 10x + 8 = 4(2x + 7)

or, 10x + 8 = 8x + 28

or, 10x - 8x = 28 -8

or, 2x = 20

or, x = 20/2

or, x = 10

x = 10

What constant do you need to add to each quadratic to complete the square? 1. x2 - 4x = 0 4 2. x2 - 8x = 6 9 3. 3x2 + 18x = 24 1
Radda [10]
1) You must add 4 to each side to complete the square.
2) You must add 16 to each side to complete the square.
3) You must add 27 to each side to complete the square.

Explanation:
1) x²-4x=0
To find the number that we add to both sides, we look at b, the cofficient of x.  It is -4. We divide it by 2 and square it; -4/2 = -2; (-2)² = 4.  This is the value that we add to both sides.

2) x²-8x=6
-8/2 = -4; (-4)²=16
We add 16 to each side to complete the square.

3) 3x²+18x=24
First we can factor a 3 out of the left side:
3(x²+6x) = 24
Our b value is now 6.  6/2 = 3; 3²=9.  The 9 would, however, go in the parentheses, so it would be multiplied by 3, which makes 27; this means we would add 27 to both sides.

A study shows that, over the course of a lifetime, the average salary of college graduates is greater than the average salary of
iogann1982 [59]
Answer: The word "ensures" implies that it is certain.

In the case of the study, they simply found that the average salary is greater for college graduates. This doesn't mean that in every case the college graduate makes more money.

The problem is the word "ensures". Our study doesn't show certainty only a general pattern.
