<span>the tens digit = n
</span><span>the units digit = n-5
n + n-5 = 9
2n = 9+5
2n = 14
n = 7  </span>←  the tens digit
the units digit = n-5 = 7 - 5 = 2
<span>the number is 72</span>

Answer:
   3 minutes
Step-by-step explanation:
Let x represent Alysha's time to drive home from the market.
Speed and time are inversely proportional to each other (for the same distance), so we have ...
   (walking speed)(walking time) = (driving speed)(driving time)
   5(x +21) = (8·5)(x)
   x +21 = 8x . . . . . . . . . divide by 5
   21 = 7x . . . . . . . . subtract x
   3 = x . . . . . . .divide by 7
It takes Alysha 3 minutes to drive home from the market.
 
        
             
        
        
        
Supplementary angles measure 180°. Make an equation:

Subtract 28 to leave the variable in the parentheses alone:

Add the 2 x's together:

Your new equation is:

Divide both sides by 2 to leave the variable alone

The supplement measures 76°
