Using elimination method. Using substitution will cause some fraction problems.
c- child tickets
a- adult tickets
4a + 7c = $83
5a + 6c = $90
multiply by -5
-20a - 35c = -$415
20a + 24c = $360
-11c= -$55
c = $5 child tickets
4a + 7(5)= $83
4a + 35 = $83
4a = $48
a= $12 adult tickets
Answer:
Hello! answer: y = 76
Because there vertical angles they Will have the same measure therefore y = 76 Hope that helps!
Answer:
230
Step-by-step explanation:
12 sections total
5 red, 4 green, the rest black
12-5-4 = 3 sections are black
3/12 = 1/4 of the sections are black
1/4 represents the probability of landing on black for one spin
(1/4)*921 = 230.25 which rounds to 230
We expect to land on a black section about 230 times out of 921 times total.
Answer:
A 34
Step-by-step explanation:
The measure of the angle is 1/2 the measure of the larger arc - 1/2 the measure of the smaller arc
VXY = 1/2( VZ - WY)
= 1/2( 93-25)
=1/2 (68)
=34
6x^-12 - 6y^3 ... I think
