<h3><u>The value of x is equal to -2.</u></h3>
5(2x + 8) = -8x + 4
<em><u>Distributive property.</u></em>
10x + 40 = -8x + 4
<em><u>Add 8x to both sides.</u></em>
18x + 40 = 4
<em><u>Subtract 40 from both sides.</u></em>
18x = -36
<em><u>Divide both sides by 18</u></em>
x = -2
Answer:
Option D) 340
Step-by-step explanation:
We are given the following in the question:
Alpha, α = 0.05
Population standard deviation, σ = $47
Margin of error = 5
95% Confidence Interval:
Putting the values, we get,
Thus, the correct answer is
Option D) 340
Answer:
1. 0.35 miles per minute
2. 5.25 miles
Step-by-step explanation:
1. speed is 21 miles per hour
speed per minute = 21/60 = 0.35 miles per minute
2. distance covered in 15 minutes = 15*0.35
= 5.25miles
This problem cannot be solved unless we are given figure NPQR is a rhombus.
In that case, then all sides are equal, meaning
5x+16=9x-32
Solve for x
9x-5x=16+32
4x=48
x=12
Each side (including PQ) then equals 5x+16=5*12+16=76
<span>Triangle is 180 degrees, so you will subtract 50 from 180 which will give you 130.</span>
