Answer:
y+x=31, 150x+225y=5100.
y=-x+31
150x+225(-x+31)=5100
-75x=-1875
x=25 (adult tickets are $25)
31-25= 6 (child tickets are $6)Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Simplifying radicals is similar to collecting like terms in algebra.
Here, the like terms are the radicals
Given
4
+ 2
- 
=
(4 + 2 - 1 )
= 5
→ B
Hi I don't know has to do this
<h3>

is the recursive formula of the geometric sequence</h3>
<em><u>Solution:</u></em>
<em><u>Given geometric sequence is:</u></em>
-0.6, 3 , -15, 75
We have to frame the recursive formula
Find the common ratio

Thus common ratio is -5
<em><u>The nth term of geometric sequence is given as:</u></em>

Where,
n is the nth term
a is the first term of sequence
r is common ratio
From sequence,
a = -0.6
r = -5
Therefore,

Where, n = 1 , 2 , 3 , 4 , .....
Thus the recursive formula is found
