a concession stand is selling hot dogs and hamburgers during a game. at halftime they sold a total of 78 hot dogs and hamburgers
lara31 [8.8K]
Let x=number of hamburgers sold and y=number of hot dogs sold.
Step 1)
cost of burgers X # of burgers + cost of hotdogs X # of hotdogs=$ collected               1.5x + 1.25y=105.5

step 2)
# of burgers sold + number of hot dogs sold = total number of items sold
     x + y = 78

step 3)  solve for y in the second equation
     y = 78 - x

step 4)  substitute y = 78 - x in the first equation for the value of y and solve for x
     1.5x + 1.25(78 - x)=105.50
     1.5 x + 97.5 - 1.25x=105.50
     .25x = 8
     x = 32


step 5)  plug in our value for x in the second equation and solve for y
     x+y=78
     32+y=78
     y=46

answer       32 hamburgers and 46 hot dogs

khan academy is giving me only this explanation but won't go into detail and I cannot understand it for the life of me. how do I
Setler [38]

Answer:

12 - 4i

Step-by-step explanation:

-2i ( 2+6i)

Distribute

-2i * 2 + -2i *6i

-4i - 12 i^2

We know that i^2 = -1 so replace it

-4i - 12(-1)

-4i + 12

Then put in the order a+bi  where the real number comes first and the imaginary number comes last

12 - 4i

The graph of y = x^2 is translated 1 unit to the right. What is the equation of the new graph?
Burka [1]

Answer: 2

Step-by-step explanation:

If the number was OUTSIDE the exponents it represents a movement up or down

If the number is inside the parenthesis and exponent ex: (x-1)^2 then it decides a movement on the left or right

However inside the parenthesis it is reversed, so a - is move to the right and a + is moved to the left, this making your answer (x-1)^2

T is the midpoint of KL. K has coordinates (2,−6), and T has coordinates (−4,2). Identify the coordinates of L.
kotykmax [81]

Answer:

L = (-10,10)

Step-by-step explanation:

Given

K = (2,-6)

T = (-4,2)

Required

Determine the coordinates of L

Since T is the midpoint of K and L, we make use of:

T_x = \frac{K_x + L_x}{2}

and

T_y = \frac{K_y + L_y}{2}

Solving for L_x

T_x = \frac{K_x + L_x}{2}

-4 = \frac{2 + L_x}{2}

Multiply through by 2

-8 = 2 + L_x

L_x = -8 - 2

L_x = -10

Solving for L_y

T_y = \frac{K_y + L_y}{2}

2 = \frac{-6+L_y}{2}

Multiply through by 2

4 = -6 + L_y

L_y = 4 + 6

L_y = 10

Hence: The coordinates of L is:

L = (-10,10)
