Is y = 3/2x +5/4 and -2x+8y=-25 a solution
nekit [7.7K]

Answer: x=-35/10

              y=-4

Step-by-step explanation:

y = 3/2x +5/4

-2x+8y=-25

--------------------

replace y in second equation with: y = 3/2x +5/4

-2x+8(3/2x+5/4)= -25

-2x+12x+10= -25

10x=-35

x=-35/10

x=-3.5

7+8y= -25

8y=-32

y=-4

7nadin3 [17]

Answer:

  • 12 games

Step-by-step explanation:

Let the number of games is g

<u>Total cost at Mar Vista:</u>

  • 3.5g + 2

<u>Total cost at Pinz:</u>

  • 3.25g + 5

<u>Since same amount spent in both places, we have:</u>

  • 3.5g + 2 = 3.25g + 5
  • 3.5g - 3.25 = 5 - 2
  • 0.25g = 3
  • g = 3/0.25
  • g = 12
