Answer:

x=1\\y=1

Step-by-step explanation:

Solve by substitution:

x+y=2\\-2x+4x=2

2x=2;x+y=2

Solve 2x+2 for x:

2x=2

x=2/2

x=1

Substitute 1 for x in x+y=2

x+y=2

1+y=2

y=2-1

y=1

x=1 & y=1

The volume of a cubic cardboard box is 125/8 ft3.
lina2011 [118]

Answer:

The answer is

<h2>\frac{5}{2}  \:  \:  \: feet \\</h2>

Step-by-step explanation:

Since the cardboard box is a cube all it's sides are equal

Volume(V) of a cube = l³

where l is the length of one side

From the question

V =  \frac{125}{8} \:   {ft}^{3}

The length of each side of the cardboard box is

{l}^{3} =  \frac{125}{8}   \\  \sqrt[3]{ {l}^{3} }  =  \sqrt[3]{ \frac{125}{8} }  \\ l =  \frac{5}{2}

We have the final answer as

\frac{5}{2}  \:  \:  \: feet \\

Hope this helps you

Hitman42 [59]
<span>I honestly believe that not everyone uses their phones during meetings or classes unless they are bored or simply searching for more information on the topic. These days cell phone devices are used by teachers and those conducting meetings. I've even seen preacher's pull up the Bible from their phones. So if fewer than 44 people use them that's actually good.</span>
