Notice that both equation has a 2f term in them

solve for 2f for both eqs.

2f= 736-6n
2f= 920-10n

since they both equal to 2f, yo can set them equal to each other

736-6n = 920-10n

and solve for n if you want

6n + 2f =736
10n +2f = 920

we are going to use the bottom equation to substitute

2f = -10n +920
f = -5n +460

plug it into the first equation

6n + 2(-5n + 460) = 736
-4n + 920 =736
-4n = -184
n =46

plug into either equation, we will use the second

10(46) + 2f = 920
460 + 2f = 920
2f = 460
f = 230

FINAL ANSWER

n = 46
f = 230

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

The perimeter of a rectangular painting is 312 centimeters. If the width of the painting is 64 centimeters, what is its length?

Kay [80]

Perimeter= 2L + 2W
312 cm= 2L + 2(64)
312= 2L + 128
subtract 128 from both sides
184= 2L
divide both sides by 2
92 cm= L

ANSWER: The length is 92cm.

Hope this helps! :)
