Answer:
288,40 $
Step-by-step explanation:
25,80$ / month * 48 months = 1238,40$ total payment.
1238,40$ - 950$ (borrowed) = 288,40 $ payed in interest.
<h2>Area = 80 ft²</h2><h2>------------------------------</h2>
<u>Step-by-step explanation:</u>
diagonal 1 (d1) = 5 + 5
= 10 ft
diagonal 2 (d2) = 8 + 8
= 16 ft
area of rhombus = 1/2 × d1 × d2
= 1/2 × 10 × 16
= 80 ft²

1.n represents the number of tickets she bought.
2.27.75n represents the total cost of n tickets
3.Without the handling fee Olga paid 138.75
4.To get 27.75n by itself on one side of the equation you can move 5.5 from the left to right of the equation
<u>Step-by-step explanation</u>
n is the total number of tickets Olga bought.
27.75n represents the total cost of n tickets.It is given in the question that one ticket costs $27.75 and thus n number of tickets will cost $27.75 n.
The handling fee is 5.5
27.75n+5.5=144.25
27.75n=144.25-5.5=138.75
without the handling fee Olga will pay $138.75
In the matrix, the first row is exactly twice the second. This implies that the determinant is zero.
If the matrix system has determinant zero, the system has either no solutions or infinite solutions.
However, just like in the matrix, in the constant vector the first term is twice the second. This means that the system has infinite solutions.
In fact, if you write this system in expanded form, you can see that it generates two equations, the first being twice the second:
