See the attached picture for 2 options for question 1 and 2 depending on how the fractions are written.


Question #3:

17 = -13 - 8x

Add 13 to each side:

30 = -8x

Divide both sides by -8:

X = 30 / -8

X = -3 3/4

Your father earned​ $34,000 per year in 1984. To the nearest​ dollar, what is that equivalent to in 2014 if the CPI in 2014 is 2
xeze [42]

Answer:

The answer is : 70288.46

Step-by-step explanation:

Your father earned​ $34,000 per year in 1984.

The CPI in 2014 is 215 and the CPI in 1984 is​ 104.

The CPI or consumer price index examines the weighted average of prices of goods and services like transportation, food etc.

The Current income equivalent will be = value in 1984 X ( CPI in 2014/CPI in 1984)

34000\times\frac{215}{104} = 70288.46

Elena-2011 [213]
X+(x+18)=$56
56-18=38
38/2=19

She spent $19 on accessories
19+18= $37 on clothes
$37+$19=$56

Hello,

m\ \widehat{ABC}=x\\m\ \widehat{BAC}=2*x\\\\So:\\ x+2x=90^o\\x=30^o\\

cos(30^o)=\dfrac{\sqrt{3} }{2} \\

In the triangle ABC,

cos(30^o)=\frac{BC}{BA} \\\\BA=\dfrac{cos(30^o)}{BC} \\\\BA=\frac{\dfrac{\sqrt{3} }{2} }{24} =16*\sqrt{3} \\\\

sin(30^o)=\dfrac{1 }{2} =\dfrac{AC}{AB} \\\\AC=\dfrac{1}{2} *16\sqrt{3} =8\sqrt{3}

In the triangle ACB,

cos(30^o)=\dfrac{AC}{AL} \\\\AL=\dfrac{8\sqrt{3} *2}{\sqrt{3} } =16\\
