1/3(x + 2) = 2/3x + 4
olga_2 [115]

For this case we have the following equation:

\frac {1} {3} (x + 2) = \frac {2} {3} x + 4

We apply distributive property on the left side of the equation:

\frac {1} {3} x + \frac {2} {3} = \frac {2} {3} x + 4

Subtracting \frac {2} {3} x from both sides of the equation:

\frac {1} {3} x- \frac {2} {3} x + \frac {2} {3} = 4\\- \frac {1} {3} x + \frac {2} {3} = 4

Subtracting \frac {2} {3}from both sides of the equation:

- \frac {1} {3} x = 4- \frac {2} {3}\\- \frac {1} {3} x = \frac {12-2} {3}\\- \frac {1} {3} x = \frac {10} {3}

We multiply by 3 on both sides of the equation:

-x = \frac {10} {3} * 3\\-x = 10

We multiply by -1 on both sides of the equation:

x = -10

The solution of the equation is x = -10

ANswer:

x = -10

Write the equation of the line perpendicular to y= 2/5x+6/6 that passes through the point (-2,6)
Oliga [24]
The line to find: y = mx + b
the line perpendicular to y= 2/5x+6/6 so it has the slope m × 2/5 = -1
thus the slope m = -5/2
the line passes through the point (-2,6) so:
6 = (-5/2)×(-2) + b so b = 1


the equation of the line is y = -5/2x +1

$1,200=to repair his home
21%=interest
$121=every month
12=month

21. X
——= ———-
100. 1200
Cross multiply
21*1200=25200
100*x=100x
25200/100=252
So Loki paid $252 interest
