Answer:

1st number: 0

2nd number: 17

Step-by-step explanation:

3x+2y=34 x is the first number, y is the second.

1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.

x+4y=68 solve for x.

x=68-4y add this into the first equation to solve for variable y.

3(68-4y)+2y=34 solve for y.

204-10y=34

-10y= -170

y=17

now to solve for x

x= 68-4(17)

x= 0

Can someone help me with this pls?
Pavlova-9 [17]

Answer:

1176cm^{3}

Step-by-step explanation:

First, calculate the volume as if it was a full rectangle.

Volume formula:

length x width x height

16 x 6 x 21 = 2016cm^{3} (this is the volume if this was a full rectangle)

Now to calculate the size of the missing part we do the same thing

10 x 6 x 14 = 840cm^{3}

To work out the volume of this shape, we need to subtract the volume of the missing part from the volume of the rectangle

2016 - 840 = 1176cm^{3}

I hope this helped :-)

What is the solution to the linear equation?<br>2/5 + p = 4/5 + 3/5p​
N76 [4]

Answer:

<h2>p = 1</h2>

Step-by-step explanation:

\frac{2}{5}  + p =  \frac{4}{5}  +  \frac{3}{5} p

Multiply through by the LCM

The LCM for the equation is 5

That's

5 \times  \frac{2}{5}  + 5p = 5 \times  \frac{4}{5}  +  \frac{3}{5}p  \times 5

We have

2 + 5p = 4 + 3p

Group like terms

5p - 3p = 4 - 2

2p = 2

Divide both sides by 2

We have the final answer as

<h3>p = 1</h3>

Hope this helps you
