Show how you solve the following two equations:<br> x – 15 = 32<br> x – 7.2 = 23.1

Lapatulllka [165]

Х - 15 = 32
х = 32 + 15
x = 47 (answer)
-----------------------
47 - 15 = 32
32 = 32

х - 7.2 = 23,1
х = 23,1 + 7.2
х = 30,3 (answer)
---------------------------
30,3 - 7,2 = 23,1
23,1 = 23,1

If y varies directly as (x+3) and inversely as (x-3) and y=21 when x=4, what is the equation for y in terms of x?

igor_vitrenko [27]

$\bf \qquad \qquad \textit{double proportional variation}
\\\\
\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}
\end{array}\implies y=\cfrac{kx}{z}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\$

$\bf \textit{\underline{y} varies directly as (x+3) and inversely as (x-3)}\implies y=\cfrac{k(x+3)}{x-3}
\\\\\\
\textit{we also know that }
\begin{cases}
y=21\\
x=4
\end{cases}\implies 21=\cfrac{k(4+3)}{4-3}\implies 21=\cfrac{k(7)}{1}
\\\\\\
\cfrac{21}{7}=k\implies 3=k\qquad thus\qquad \qquad \boxed{y=\cfrac{3(x+3)}{x-3}}$

Slove 3/4(5x-3)+8=17. Show your work

Vlada [557]

So first you would simplify 3/4(5x-3) to 3(5x-3)/4
So it would be 3(5x-3)/4+8=17
2. Subtract 8 from both sides
3(5x-3)/4=17-8
3. Then simplify 17-8 to 9
3(5x-3)/4=9
4. Multiply both sides by 4
3(5x-3)=9x4
5. Simplify 9x4 to 36
3(5x-3)=36
6. Divide both sides by 3
5x-3=36/3
Simplify 36/3 to 12
5x-3=12
8. Add 3 to both sides
5x=12+3
9. Simplify 12+3 to 15
5x=15
10. Divide both sides by 5
X=15/5
Simplify 15/5 to 3
X=3
So your answer is x=3
