Answer:

x = 1

y = -24

Step-by-step explanation:

8x + y = -16

-3x + y = -5

Subtract equation one from equation two

8x - -3x + y - y = -16 - - 5

8x + 3x = -16 + 5

11x = 11

Divide both sides by 11

11x/11 = 11/11

x = 1

Now substitute 1 for x in either of the equations to get y.

Using equation one, we have

8x + y = -16

8 x 1 + y = -16

8 + y = -16

Subtract 8 from both sides

8 - 8 + y = -16 - 8

y = -24

x = 1

y = -24

A flying disc has a 5 ⅖ inch radius. What is its approximate circumference, rounded to the nearest inch?
Ivenika [448]
<h2>Circumference of flying disc is 34 inches</h2><h3><u>Solution:</u></h3>

Given that,

Radius = 5\frac{2}{5}\ inches = \frac{27}{5}\ inches

To find: circumference

<h3><u>The circumference of circle is given as:</u></h3>

C = 2 \pi r

Where, r is the radius of disc

Therefore,

C = 2 \times 3.14 \times \frac{27}{5}\\\\C = 6.28 \times 5.4\\\\C = 33.912

C \approx 34

Thus the circumference of flying disc is 34 inches

Solve the system x + 7y = 16 and 3x - 7y = 4 for x. *
Fudgin [204]

Answer:

x=5

Step-by-step explanation:

To start solving this, you want to solve an equation for y. I chose 3x - 7y = 4 for later purposes. Subtract 3x from both sides and divide by -7 to get y = 4 - 3x / -7. Now because we have a value for y in terms of x, plug this into the other equation, x + 7y = 16. It now should look like this: x + 7(4 - 3x / -7) = 16. Now just distribute the 7 and simplify the denominator to get x+ (-4+3x)=16. This can now be 4x +4 = 16, starting to look familiar now. Lastly subtract the 4 from both sides and divide by 4 to get x = 5. Hope this helps!
