Answer:

1/0.7

Step-by-step explanation:

The expression x-y equals to 0.7 so we have to substitute 0.7 in the place of x-y....

What steps do I do to answer this

Gnesinka [82]

Your equation is: 5h + 4 = 10h + 8

First subtract 5h from both sides:(So that variable terms stays in one side only)

=> 5h + 4 -5h = 10h + 8 -5h

=> 4 = 5h + 8

Now subtract 8 from both sides:(So constant term stays in the opposite side of variable terms)

=> 4 - 8 = 5h + 8 - 8

=> -4 = 5h

Now divide both sides by 5:(division by coefficient of variable)

=> -4/5 = 5h/5

=> -4/5 = h

=> h = -4/5 = -0.8

Rashid [163]

Answer:

$A = L W= 9*\frac{9}{2}=\frac{81}{2} m^2$

Step-by-step explanation:

For this case we assume that the total perimeter is 18 ft, we have a wall and the two sides perpendicular to the wall measure x units each one so then the side above measure P-2x= 18-2x.

And we are interested about the maximum area.

For this case since we have a recatangular area we know that the area is given by:

$A= LW$
