A $40 jacket is on sale for 30% off what is the sale price

Sergeeva-Olga [200]

So 40=100%
find 100%-30%=70%
70% of 40
'of' can be translated to multiply
70% times 40
percent means parts out of 100 so
70%=70/100=7/10=0.7
so
.7 times 40=28
the sale price=$28

5x=(2x-2)(m+6) Solve for x

coldgirl [10]

Answer:

Step-by-step explanation:

hello :

5x=(2x-2)(m+6) equivalent : 5x = 2xm+12x-2m-12

5x-2xm -12x=-2m-12

x(5-2m-12) = -2m-12

x(-7-2m) = -2m-12

x(2m+7) = 2m+12

if : 2m+7 ≠ 0 means m ≠ -7/2 so : x= (2m+12)/(2m+7)

if : 2m+7 = 0 means : m = -7/2 you have : x(0) = 2(-7/2)+12

0= 5 ( false) ... x no exist
