Hank spend 76% of his monthly salary and saves $270 find his monthly salary

Dimas [21]

Answer:

f $270= the remaining 24% then you want to do 270/24=11.25 Then you want to multiply that by 76 and you will get $855

So $270+$855=24%+76% So his monthly salary was $1,125

If you are still confused do it in reverse! 1,125/100=11.25

11.25•24=270 & 11.25•76=855

270+855=1,125

What dose 2+7x=5x+14 equal

weqwewe [10]

Answer:

$x=6$

Step-by-step explanation:

$2+7x=5x+14$

Subtract 2 from both sides:

$2+7x-2=5x+14-2$

$7x=5x+12$

Subtract 5x from both sides:

$7x-5x=5x+12-5x$

$2x=12$

Divide both sides by 2:

$\frac{2x}{2}=\frac{12}{2}$

$x=6$
