1092...if 4 out of 7 named blue then

1092 * 4/7 = 624 (named blue)

1092...if 1 out of 3 named red then

1092 * 1/3 = 364 (named red)

364 + 624 = 988 (both named red and blue)

1092 - 988 = 104( neither named red nor blue)

answer is 104 people

How to sustitute 6n+2f=736 and 10n+2f=920
Ahat [919]
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

Please Help! Simple Geometry!
marta [7]

Answer:

A     32.1

Step-by-step explanation:

Given two points (x_{1} ,y_{1} ) and (x_{2} ,y_{2}))

distance between to points = d = \sqrt{(x_{2} - x_{1} )^{2} + (y_{2} - y_{1} )^{2} }

Now B is (-4,5) and A is (2,0)

So AB = \sqrt{(-4-2)^{2} +(5-0)^{2} }  = \sqrt{36 + 25} = \sqrt{61\\} = 7.810...

C is (4,10)

So BC = \sqrt{(-4-4)^{2} +(5-10)^{2} } =\sqrt{64 + 25) } =\sqrt{89} =9.433...

D is (8,7)

So CD = \sqrt{(4-8)^{2} +(10-7)^{2} } =\sqrt{16 + 9} = \sqrt{25} = 5

E is (4,5)

So DE = \sqrt{(8-4)^{2} + (7-5)^{2} }  = \sqrt{16 + 4}  = \sqrt{20}  =  4.472...

and AE = \sqrt{(4-2)^2 + (5-0)^2} =\sqrt{4+25}  = \sqrt{29} = 5.385...

Perimeter = 7.810 + 9.433 + 5 + 4.472 + 5.385 = 32.1
