M is the midpoint of PQ. MQ = 5x + 8 and PQ = 6x + 56, find PM.

(4 Points)

Enter your answer

Answers

If M is the midpoint of PQ. MQ = 5x + 8 and PQ = 6x + 56, then PM = 58

Since M is the midpoint of PQ

PM  +   MQ   =   PQ................(*)

Given:

PQ  =  6x + 56

MQ  = 5x + 8

Substitute PQ and MQ into equation (*)

PM   +  (5x + 8)  =  6x  +  56

Collect like terms

PM   =  6x  +  56  -   (5x  +  8)

Expand the equation using the distributive rule

PM  =  6x  +  56  -  5x  -  8

PM  =  6x  -  5x  +  56  -  8

PM  =  x  +  48.........(**)

Equate MQ and PM

MQ   =   PM

5x  +  8    =   x  +  48

Collect like terms

5x  -  x  =  48  -  8

4x   =   40

Divide both sides by 4

4x / 4   =  40/4

x   =   10

Substitute x = 10 into equation (**)

PM  =  x  +  48

PM  =  10  +  48

PM   =  58

solve the compound inequality-8 < 5x + 7 <2

Answers

Answer:

-3 < x ≤ -1

Step-by-step explanation:

-8 < 5x + 7 ≤ 2

First, subtract 7 from all sides of the inequality:

-8 - 7 < 5x + 7 - 7 ≤ 2 - 7

-15 < 5x < -5

Divide all sides by 5 to isolate x:

-15 ÷ 5 < 5x ÷ 5 ≤ -5 ÷4

-3 < x ≤ -1

What is the decimal equivalent of 4/5

Answers

Answer:

0.8

Step-by-step explanation:

to find the decimal equivalent we must get the denominator to 100

to do that we must multiply it by 20, 4/5 * 20/20 is 80/100

80/100 is also 80%, which is also 0.80 (which can be simplified to 0.8)

Answer:

First option: y = 5/6x + 12

Step-by-step explanation:

In the slope-intercept form, y = mx + b:

m = represents the slope

b = represents the y-coordinate of the y-intercept, (0, b).

In your given question, it states that the slope (m) = 5/6, and the y-intercept is (0, 12). This means that the value of (b) for your linear equation is the y-coordinate of (0, 12). Therefore, the correct answer is:

y = 5/6x + 12
