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

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

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)

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
