variables d and w
5d +1(4d)=36
9d=36
d=4 w=4x4=16
difference of price $12
5)
E 5 comics
F= 10
G=20
e+ (e+5) + 2(e+5)=35
e+ e+5 + 2e +10 =35
4e +15=35
4e=20
e=5

Agnes and Billy had each 300 (after drinking it will be less water)
A 300-200 =100
B 300-100 =200
Answer: 24^p
Step-by-step explanation:
8 ^p x 3
To simplify the above, multiply the whole numbers
8 x 3 = 24
24^p
Because the vertex of the parabola (0,0), focus is moved to the left, and x -coordinate is changed. So, it is horizontal parabola that is looking to the left.
It is horizontal parabola, so it has y².
<u>Answer:</u>
a(n) = 130 + (n-1) 13
13th term = 286
<u>Step-by-step explanation:</u>
We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.
We know that the arithmetic sequence can be defined by:

where
= the common difference between consecutive terms ; and
=
<u>13th term:</u>

Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.
