5/6 + 3j = -2/3 I need to find the value of j

weeeeeb [17]

5/6 + 3j = -2/3

Multiply all terms by 3.

5/2 = 3j - 2

Multiply all terms by 2.

5 = 6j - 4

Add 4 to both sides.

9 = 6j

Divide both sides by 6.

j = 1.5

Which ratio is smaller 3/5 or 7/10

Oksanka [162]

3/5=6/10

So 6 being smaller than 7 means 3/5 is smaller than 7/10

By what percent has the rhinoceros weight increased

romanna [79]

let's first off convert those mixed fractions to improper fractions, then get their difference.

$\bf \stackrel{mixed}{1\frac{1}{2}}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}}~\hfill \stackrel{mixed}{2\frac{1}{10}}\implies \cfrac{2\cdot 10+1}{10}\implies \stackrel{improper}{\cfrac{21}{10}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{21}{10}-\cfrac{3}{2}\implies \stackrel{\textit{using the LCD of 10}}{\cfrac{(1)21-(5)3}{10}}\implies \cfrac{21-15}{10}\implies \cfrac{6}{10}\implies \cfrac{3}{5}$

now, the original amount, 3/2, if that is the 100%, what is 3/5 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2}\\ \frac{3}{2}&100\\\\ \frac{3}{5}&x \end{array}\implies \cfrac{~~\frac{3}{2}~~}{\frac{3}{5}}=\cfrac{100}{x}\implies \cfrac{3}{2}\cdot \cfrac{5}{3}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40$

Find the measure of ∠C if ∠A = 3 2 x + 20 ∠B = 7 2 x + 20 ∠C = 5 2 x + 40 ∠D = 3 2 x + 10 A) 65° B) 76° C) 95° D) 115°

Rudiy27

The sum of the angles of a quadrilateral is 360°.
$\left(\dfrac{3}{2}x+20\right)+\left(\dfrac{7}{2}x+20\right)+\left(\dfrac{5}{2}x+40\right)+\left(\dfrac{3}{2}x+10\right)=360\\\\9x+90=360\\\\x=\dfrac{270}{9}=30$

Given that x=30, the measure of ∠C is
∠C = (5/2)×30 +40 = 115

The appropriate choice is ...
D) 115°

It's an expression that can be simplified to read

( 0.7 x 0.4 ) ( b³ x b⁹ )

= ( 0.28 ) ( b¹² ) = 0.28 b¹² .
