Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16

Answer: x = 30' , y = 45'

hope this helps

Step-by-step explanation:

U is 90' it's a right triangle

well simple VRT you already know 2 angles which is 60' and 90'

R = 60'

V = 90'

T = x

you know that a triangle = 180'

so you do

180 - 60 - 90 = x

30 = x

if you want to do y

then you already know that U is 90' on both sides.

since you also know S,

S = 45'

U = 90'

V = y

180 - 90 - 45 = y

45 = y

a circus charges $2.50 for kids tickets and $6 for adult tickets last week and twice as many kids attended the circus than adult
aliina [53]
Let
x-----------> the number of kids
y----------> the number of adults

we know that
2.5x+6y=$7150---------> equation 1
x=2y-------------> equation 2
substitute 2 in 1
2.5*[2y]+6y=7150-----> 5y+6y=7150----> 11y=7150-----> y=650
x=2y----> x=2*650----> 1300

the answer is
the number of kids is 1300
