MAX POINTS!!! Write and solve a system of equations. Be sure to label the variables. The difference of two numbers is two. Two t
Cerrena [4.2K]

Answer:

  • 5 and 3

Step-by-step explanation:

Let the numbers be x and y.

<u>The equations are:</u>

  • x - y = 2
  • 2x + y = 13

<u>Add up the equations to eliminate y and solve for x:</u>

  • x - y + 2x + y = 2 + 13
  • 3x = 15
  • x = 15/3
  • x = 5

<u>Now find the value of y:</u>

  • y = x - 2
  • y = 5 - 2
  • y = 3

A waitress sold 12 ribeye steak dinners and 39 grilled salmon totaling $575.53 on a particular day. Another day she sold 25 ribe
Talja [164]

Answer:

cost of ribeye steak dinners = $10.36

cost of grilled salmon= $11.581

Step-by-step explanation:

Let the cost of one steak dinners be x

Let the cost of one  grilled salmon be y

One a particular day the waitress sells  12 ribeye steak dinners and 39 grilled salmon for a total is $575.53 which can be written in equation as

12(x)+39(y)= $575.53-------------------------------------(1)

On another day she sells  25 ribeye steak dinners and 13 grilled salmon dinners  totals to $582.43.This can be represented  as

25(x)+ 13(y)= $582.43-------------------------------------(2)

solving the equation (1) and (2)

eq(1) x 112x+39y= 575.53

eq(2) x 3125x+ 39y= 1747.29-------------------------(3)

Subtracting these equation we get,

113x=1171.76

x=\frac{1171.76}{113}

x= 10.36

Now  substituting this in equation (1)

12(10.36)+39(y)= $575.53

123.84+39y=575.53

39y=575.53 - 123.84

y=\frac{451.69}{39}

y=11.581
