Let
z--------> the number

we know that
<span>One third of a number, z, added to one fifth of the same number is 3/5 
</span><span>so
the equation that represents this sentence is 
</span>(1/3)z+(1/5)z=3/5
(5+3)z/15=3/5----------> 8z=9-------> z=9/8

therefore

the answer is the option
<span>D) 9/8 , because the equation that represents this sentence is 1/3z+1/5z=3/5 .</span>

If the side length of a cube is 40 what is the surface area
Elodia [21]
A cube has 6 sides.

A cube is all made up of squares.

So, we need to find the area of one cube and multiply that by 6.

Length * width= area

40*40= 1,600

Multiply that by 6.

1,600*6= 9600

Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.

9,600 (the unit) ^2

I hope this helps!
