Can someone solve this for me?

Helga [31]

well, we know it's a rectangle, so that means the sides JK = IL and JI = KL, so

$\stackrel{JK}{3x+21}~~ = ~~\stackrel{IL}{6y}\implies 3(x+7)=6y\implies x+7=\cfrac{6y}{3} \\\\\\ x+7=2y\implies \boxed{x=2y-7} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{JI}{6y-6}~~ = ~~\stackrel{KL}{2x+20}\implies 6(y-1)=2(x+10)\implies \cfrac{6(y-1)}{2}=x+10 \\\\\\ 3(y-1)=x+10\implies 3y-3=x+10\implies \stackrel{\textit{substituting from the 1st equation}}{3y-3=(2y-7)+10} \\\\\\ 3y-3=2y+3\implies y-3=3\implies \blacksquare~~ y=6 ~~\blacksquare ~\hfill \blacksquare~~ \stackrel{2(6)~~ - ~~7}{x=5} ~~\blacksquare$

A pair of jeans cost $32 last year this year they cost $38 what was the percent increase? PLEASE ANSWER NEED HELP!

garik1379 [7]

Answer:

18.75%

Step-by-step explanation:

percent increase = $\frac{increase}{original cost}$ × 100%

Increase in cost = $38 - $32 = $6

percent increase = $\frac{6}{32}$ × 100% = $\frac{6(100)}{32}$ = 18.75%

Answer:

<h2>-1</h2>

Step-by-step explanation:

$2x + 7 - 1 = 2x + 7$

$= > 2x - 1 = 2x + 7 - 7$

$= > 2x - 1 = 2x$

$= > - 1 = 2x - 2x$

$= > x = - 1$
