Marci went to the state fair with her friends. The total cost of tickets for rides is given by the equation c=2.75t where c is t

snow_tiger [21]

Answer:

c = 55 . . . . (no units for cost are given in your problem statement)

Step-by-step explanation:

"t is the number of tickets" and "Marci bought 20 tickets", so we conclude t=20. Putting that value into the equation and doing the arithmetic, we find ...

c = 2.75·20 = 55

_____

We don't know if this is pennies or pounds, dollars or rupees or pesos or euros. No monetary units are mentioned in the problem statement given here.

A system of linear equations with more equations than unknowns is sometimes called an overdetermined system. Can such a system b

shepuryov [24]

Answer:

A. Yes, overdetermined systems can be consistent.

As, the system of equations below is consistent because it has a solution

$x_{1}=2$ , $x_{2}=4$ , $x_{1}+x_{2}=6$ .

Step-by-step explanation:

We have,

'Over-determined system is a system of linear equations, in which there are more equations than unknowns'.

For e.g. Let us consider the system,

2x - 3y = 1

3x - 2y = 4

x - y = 1

Plotting these equations, we see from the graph below that,

The only intersection point is (2,1). Thus, x= 2 and y= 1 is the solution of this system.

Thus, over-determined system can be consistent.

According to the options,

Option C is not correct as,

$x_{1}=2$ , $x_{2}=4$ implies $x_{1}+x_{2}=2+4=6\neq 8$ .

Hence, option A is correct.

What is -3(2 - x) = 9x

Romashka [77]

Answer:

-1=x

Step-by-step explanation:

You multiply the -3 into the (2-x). which gives you -6+3x=9x. Know you wanna get ride of the 3x so you subtract from both sides, which then gives you. -6=6x. From here were gonna need to get x by itself so you divide both sides by 6.
