Answer:
is congruent because are parralel
<span>4(x+5) = 4x +5x
Simplify by distributing and combining like terms
</span>(4)(x)+(4)(5)=4x+5x
4x+20=4x+5x
4x+20=(4x+5x)
4x+20=9x
Subtract 9x from each side
4x+20−9x=9x−9x
5x+20=0
<span />
Subtract 20 from each side
−5x+20−20=0−20
−5x=−20
Divide each side by -5
-5x ÷ -5 = -20 ÷ -5
x = 4
P.S this was actually harder than most algebra problems, so don't beat yourself about it :D<span /><span /><span /><span /><span />
This non-question cant be answered without knowing what the table looks like
Answer:
Subtract 1/2 from both sides of the equation.
w=1/4w+1 1/2
Multiply both sides by 4
4w=w+6
Subtract w from both sides
3w=6
Divide both sides by 3
w=2
Check answer
2+1/2=1/4(2)+2
2 1/2=2 1/2
Step-by-step explanation:
Absolute deviation is 92.40
Rearrange numbers from least to greatest to avoid confusion.
108, 112, 122, 145, 160
Mean = (108 + 112 + 122 + 145 + 160) / 5
= 647 / 5
= 129.40
Absolute deviation : (number - mean)
*absolute means that a number is always treated as a positive number contrary to its actual value
108 - 129.40 = 21.40
112 - 129.40 = 17.40
122 - 129.40 = 7.40
145 - 129.40 = 15.60
160 - 129.40 = <u> 30.60</u>
total absolute deviation 92.40
Mean absolute deviation = 92.40 / 5 = 18.48
