15 cards = 9$
1 card = (9/15)$
12 cards = 9/15 * 12
= 108/15
= 7.2$
Answer:
They are supplementary angles so they add up to make 180°
So you do the reverse
180°-100°=x
80°=x

Answer:
Step-by-step explanation:
y = a(b)^x
a would represent the initial value.
b would represent the change
x represents the number of years
y = 805(0.9)^6
y = 805(0.531441)
y = 427.8
y = 427 cheetahs
F(9)=3(9)-6
f(9)=27-6
f(9)=21
Answer:
a:b = 3:5
Step-by-step explanation:
As a:b is required, divide both terms by b
5a:b + 3b:b = 6b:b
5a:b + 3 = 6
5a:b = 6 - 3
5a:b = 3
a:b = 3:5
