Answer:

3x+2y=315\\\\2x+4y=450

is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2  haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

<u><em>Let the number of haircuts be </em></u>x.<u><em /></u>

<u><em>Let the number of hair dyes be </em></u>y.<u><em /></u>

So, Alexandra can give 3 haircuts and 2 hair dyes in:

3x+2y=315.

Now, giving 2 haircuts and 4 hair dyes in:

2x+4y=450.

Therefore,

3x+2y=315\\\\2x+4y=450

is the system of equations representing the situation.

THE ANSWER TO THE TOP LINE IS: 140

Step-by-step explanation:

why? becuase 10 times 10 is 100 all whole fractions need to be ?/100 (something over 100) so then becuase you did 10 times ten to find what 14 is you do 14 times 10. it should look like this :D.

10*10=100

14*10=140 .         140/100 is your answer or 140 :)

One equation in a linear system of two equations is 3x - 2y = 8. the system has an infinite number of solutions. which could be
kumpel [21]

The equation 3x - 2y = 8 and 6x - 4y = 16 are systems of equations with infinite solutions.

A linear system of equations can have (a)unique solutions, (b) infinite number of solutions, or (c) no solution.

For it to have infinite number of solutions, the graph of the equations must intercept with each other at infinite points, leaving the two graphs overlaying each other.

Given the equation, 3x - 2y = 8, the other equation in a linear system to have infinite number of solutions with it must be the exact same line.

To do this, simply multiply the whole equation with a real number.

Example:

Multiplying the whole equation by 2 gives 6x - 4y = 16.

Now, 3x - 2y = 8 and 6x - 4y = 16 are equations in a linear system with infinite number of solutions.
