E=number of eagles
c=number of condors

ttoal is 480
c+e=480

5 times as many condors and 9 times as many eagles totals 3260
5c+9e=3260


we have
c+e=480
5c+9e=3260

eliminateion
elmiminate c
times first equation by -5

-5c-5e=-2400

add to other equation

-5c-5e=-2400
<u> 5c+9e=3260 +</u>
0c+4e=860

4e=860
divide both sides by 4
e=215

sub back

c+e=480
c+215=480
minus 215 from both sides
c=265


thiis spring is

265 condors
215 eagles

Can anyone help me with this?
yawa3891 [41]

Answer:

Below.

Step-by-step explanation:

7)  c^2 = a^2 + b^2

15^2 = 11^2 + b^2

b^2 = 225 - 121 = 104

b = √104

= √4√26

= 2√26.m

8). 4^2 = a^2 + (√6)^2

a^2 = 16 - 6

a^2 = 10

a =  √10.

ExtremeBDS [4]
Ok so you would plug in 18 for the x so it would be 6(18)-12 and then 6x18 is 108 and 108-12=96 so your answer is 96

58 degrees

Explanation
If you have a triangle with the angle measures of abc as 58 degrees, 102 degrees and 20 degrees you can multiply them in order of abc so 58 degrees is angle a, 102 degrees is angle b and 20 degrees is angle c. Then you just put in angle a for d which would be 58 degrees and angle e for b 102 degrees and angle f for c which would be 20 degrees
