4 mo.

Step-by-step explanation:

I = PRT P = 600 R = .0375 I = 7.50

7.50 = 600(.0375)T

7.5 = 22.5T

T = 7.5/22.5 = 1/3 yr = 4 mo.

Determine if the statement is true or false. If a linear system has the same number of equations and variables, then it must hav

lutik1710 [3]

Answer:

False

Step-by-step explanation:

Consider the equations with the same number of equations and variables as shown below,

<u>Case 1</u>

$x_{1} + x_{2} = 0\\x_{1} + x_{2} = 1$

This equation has no solution because it is not possible to have two numbers that give a sum of 0 and 1 simultaneously.

<u>Case 2</u>

$x_{1} + x_{2} = 1\\2x_{1} + 2x_{2} = 2$

This equation has infinitely many possible solutions.

Therefore it is FALSE to say a linear system with the same number of equations and variables, must have a unique solution.

Papessa [141]

Answer:

0 < x < 2

Step-by-step explanation:

0 < 2x < 4

Divide 2 into all the parts.

0/2 < 2x/2 < 4/2

The x variable should have no coefficient.

0 < x < 2

AVprozaik [17]

Answer:

Advance ticket costs $25

Same-day ticket costs $20

Step-by-step explanation:

Let x = the price of one the advance ticket.

Let y = the price of one same-day ticket.

The combined cost of one advance ticket and one same-day ticket is $ 45. This means

x + y = 45 - - - - - - 1

For one performance, 30 advance tickets and 20 same-day tickets were sold. The total amount paid for the tickets was $ 1150. This means

30x + 20y = 1150 - - - - - - - - -2

From equation 1, x = 45- y

Put x = 45- y in equation 2

30( 45-y) + 20y = 1150

1350 - 30y + 20y = 1150

-10y = 1150-1350

-10y = -200

y = 200/10 = $20

x = 45-y

x =45-20= $25

Advance ticket costs $25

Same-day ticket costs $20
