Let x be the number of movies rented 
Let y be the number of video games rented 

(5x+2y=26)4
- 3x+8y=53 

 20x+8y=104 
-3x+8y=53
-----------------
17x       =51 
x=51/17 
x=3 

5x+2y=26 
5(3)+2y=26 
2y=26-15 
y=11/2 
y=5.5 

Therefore, the movies cost $3 and the video games cost $5.5 

Hope I helped :)

Simplify 5a – (2a + 6)
Temka [501]

Answer:

Step-by-step explanation:

Add '-2a' to each side of the equation.

5a + -2a = -6 + 2a + -2a

Combine like terms: 5a + -2a = 3a

3a = -6 + 2a + -2a

Combine like terms: 2a + -2a = 0

3a = -6 + 0

3a = -6

Divide each side by '3'.

a = -2

Simplifying

a = -2

milton opens a store credit card when he purchases appliances for his kitchen. the interest rate is 17.45%. he charges $3,740 to
kari74 [83]

<u>Answer-</u>

The total cost of his purchase will be $3,846.34

<u>Solution-</u>

Here, the annual interest rate is 17.45%.

So monthly interest rate will be,

=\frac{17.45}{12} =1.454\%=0.01454

With a purchase of $3,740, the amount will be after one month,

=3740(1+0.01454)^1=3740(1.01454)=3794.38

Then she makes a payment of $1350, so the balance at the end of month 1 is

=3794.38-1350=2444.37

Now she has to pay with $2444.37 as principal amount, the amount will be after one month,

=2444.37(1+0.01454)^1=2444.37(1.01454)=2479.91

Then she again makes a payment of $1350, so the balance at the end of month 2 is

=2479.91-1350=1129.91  

Final month, she has to pay with $1129.91 as principal amount, the amount will be,

=1129.91(1+0.01454)^1=1129.91(1.01454)=1146.34

So the total cost, including interest, would be the sum of the three payments,

=1350+1350+1146.34=3,846.34

Answer:

To round 17.126 to the nearest tenth consider the hundredths’ value of 17.126, which is 2 and less than 5. Therefore, the tenths value of 17.126 remains 1.

17.126 rounded to the nearest tenth = 17.1

The following table contains starting numbers close to 17.126 rounded to the nearest 10th.
