X=6

One angle is 6 the other angle is 84

rusak2 [61]

If nthe shop has a mark up rate of 50% and they cost 300 to buy you multiply 300 by 50% convert 50% to decimal
so you do .5*300=150
then you add 150 to 300 which means that the shop sells the skis for 450 dollars.

$2x + 9 = 5x$

$5x = 2x + 9$

Subtract sides 2x

$- 2x + 5x = - 2x + 2x + 9$

$3x = 9$

Divide sides by 3

$\frac{3x}{3} = \frac{9}{3} \\$

$x = 3$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK :

$2x + 9 = 5x$

$2(3) + 9 = 5(3)$

$6 + 9 = 15$

$15 = 15$

So the value is correct.
