PLEASE HELP DUE SOON

vaieri [72.5K]

Answer:

I got 7%

Step-by-step explanation:

110 x .15 = 16.5

110-16.5=93.5

93.5 x .10 = 9.35

93.5 + 9.35= $102.82

Thats the discount price

110 - 102.82 + 7.18

7.18/102 = .0698

.0698 x 100 = 6.98

I have this on my middle school test and it's my first time doing it so yea. I hope it helps even if it's already too late.

I had to edit it beforee

$2x +y = 20~~....(i)\\\\6x -5y = -4~~....(ii)\\\\\\\text{Multiply equation (i) by 3:}\\\\6x +3y = 60~~...(iii)\\\\(iii)-(ii):\\\\6x+3y - 6x+5y = 60-(-4)\\\\\implies 8y = 60+4 = 64\\\\\implies y = \dfrac{64}8\\\\\implies y = 8\\\\\\\text{Substitute y =8 in equation (i):}\\\\2x+8 =20\\\\\implies 2x = 20-8 = 12\\\\\implies x = \dfrac{12}2 = 6\\\\\text{Hence (x,y) = (6, 8)}$

George is twice the age of Mike minus 5. The sum of George and Mike's ages is 31. How old is George and write an equation to rep

Temka [501]

Answer:

George is 19

Step-by-step explanation:

George is g and Mike is m

g = 2m - 5
g + m = 31

Substitute g in the second equation

2m - 5 + m = 31
3m - 5 = 31
3m = 36
m = 12

Finding g

g = 2*12 - 5 = 24 - 5 = 19
