Answer:

<h2>x = 14</h2><h2 />

Step-by-step explanation:

7x + 9 + 5x + 3 = 180

7x + 5x = 180 - 3 - 9

12x = 168

x = 168 / 12

x = 14

Answer:

14

Step-by-step explanation:

By applying the vertical angle theorem to 5x + 3, using same-side exterior angle theorem, we can find that:

(7x + 9) + (5x + 3) = 180

Now to find x, we can just solve for x in the equation we found.

(7x + 9) + (5x + 3) = 180

Combine like terms.

12x + 12 = 180

Subtract 12 from both sides.

12x = 168

Divide both sides by 12.

x = 14

So the value of x would be 14.

I hope you find my answer and explanation to be helpful. Happy studying.

Find the value of x and y that make the quadrilateral
vitfil [10]

The quadrilateral have equal opposite sides, for example:

Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore

4x+6=7x-3

We can solve that equation for x

\begin{gathered} 4x+6=7x-3 \\  \\ 3x=9 \\  \\ x=\frac{9}{3}=3 \end{gathered}

Hence, x = 3. Now let's solve the other equation

\begin{gathered} 4y-3=3y+1 \\  \\ y=4 \end{gathered}

Then the value of y is 4.

Final answers:

x = 3

y = 4

Nastasia [14]

Answer:

1571in^3

Step-by-step explanation:

Given data

h= 20 in

d= 10 in

r= 10/2= 5 in

V= πr^2h

substitute

V= 3.142*5^2*20

V=3.142*25*20

V=1571 in^3

Hence the volume is 1571in^3
