4.)
To solve for Y it is                To solve for X
-8y=-6x                                -8y=-6x
/-8   /-8                                  /-6  /-6
          
y=3/4(x)                                4/3(y)=x

5.) 
to solve for Y                      To solve for X
1/2(y)=4(2x-1/4)                    1/2(y)=4(2x-1/4)
1/2(y)=8x-1                            /4        /4
*2        *2                                y/8=2x-1/4
                                              +1/4     +1/4
y=16x-2                                (y/8)+1/4=2x
                                               /2           /2
                                           
                                             ((y/8)+1/4)/2=x

How do you solve 7.2>0.9(n+8.6)
labwork [276]
7.2>0.9(n+8.6)
multiply 0.9 by all in parentheses

7.2> (0.9*n) + (0.9*8.6)
7.2> 0.9n + 7.74

subtract 7.74 from both sides
-0.54> 0.9n

divide both sides by 0.9
-0.6> n

If 50 one-cent coins were stacked on top of
Sedbober [7]

To make 8 inch tall column approximately 61 coins required.

Given,

Total one cent coins stacked on top of each other in a column = 50

Height of column = 378 inches

Approximate height of one coin = ( 50 / 378)

                                                    = 0.132 inches

To make an 8 inches tall stack No of coins required will be:

Number of coins required  = ( total height / height of one coin )

                   = ( 8 / 0.132 )

                   = 60.60

                    ≅ 61 coins

To make 8 inch tall column approximately 61 coins required.
