The price of a mobile phone decreased from $375 to $250 during a clearance sale. What is the percent of decrease in the price?

Tresset [83]

So decrease is 375-250=75

so convert 75/375 to percent
percent means part out of 100 so
x/100=x%

divide 125/375=0.3333/1

multiply by 100/100=33/100=33%

the answer is 33% or B

What is the solution to the system of equations?

elixir [45]

Answer:

No solution

Step-by-step explanation:

$-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\$

Lets consider the equation 2.

Here we multiply the LHS and RHS with (-1).

$-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\$

Hence,

$-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\$

When we add the equations we get,

$0x+0y+0z=-10+9\\Hence,\\0=-1$

As 0 doesn't equal to -1, answer is d) No solution

Answer:

solution,

$- 2 = \frac{x - 17}{2} \: \\ - 2 \times 2 = x - 17 \\ - 4 = x - 17 \\ - x = - 17 + 4 \\ - x = - 13 \\ x = 13 \\ \\ 7 = \frac{y + 17}{2} \\ 14 = y + 17 \\ - y = 17 - 14 \\ - y = 3 \\ y = - 3$

Therefore,

V=(13,-3)

Hope this helps...
