Answer:
cost of each video game = $5.50
cost of each movie = $4.25.
Step-by-step explanation:
Let m represent cost per movie
g represents cost per video game.
Create two equations to represent the total cost Tammy rented movie and video games in each month, and solve simultaneously for each variable:
First month:
=> equation 1
Second month:
=> equation 2
Multiply equation 1 by 4, and multiply equation 2 by 2 to derive:
4 ×
2 ×
=> equation 3
=> equation 4
Subtract equation 4 from equation 3
You'd have:
- 4g = - 22
Divide both sides by -4
g = 5.5
Thus, the cost of each video game = $5.50.
Substitute g = 5.5 in equation 1 and solve for m.
Subtract 16.5 from each side
Divide both sides by 2
Thus, cost of each movie = $4.25.
So, the fee is 125 and...
125+
a certain fee "x"
125+x*
which is paid monthly, that is 12 times:
125+x*12
and this equals 720.
125+x*12=720
subtracting 125:
x*12=595
dividing by 12:
x=49,58
and this is how much they pay each month!
This answer would be (55/9, ∞)
Answer:
a52=64.4
Step-by-step explanation:
The formula for an arithmetic sequence is
an = a1+d(n-1)
a1 =3.2 (it is the first term)
We can find the common difference by taking the second term and subtracting the first term
4.4-3.2 =1.2
d=1.2
n = the term number we are looking for
an = 3.2 +1 .2(n-1)
We are looking for the 52nd term so n=52
a52 = 3.2 +1 .2(52-1)
= 3.2 + 1.2(51)
= 3.2+61.2
= 64.4
