Caleb and Jeremiah go to the movie theater and purchase refreshments for their
Mashutka [201]

Answer:

price of each bags of popcorn = $9.75

price of each drinks = $5

Step-by-step explanation:

Let

price of each bags of popcorn = a

price of each drinks = b

Caleb total cost

7a + 2b = 78.25.......(i)

Jeremiah total cost

a + 10b = 59.75.......(ii)

7a + 2b = 78.25

a + 10b = 59.75

a = 59.75 - 10b

insert the value of a in equation (i)

7a + 2b = 78.25

7( 59.75 - 10b) + 2b = 78.25

418.25 - 70b + 2b =  78.25

418.25 - 68b = 78.25

418.25 - 78.25 = 68b

340 = 68b

b = 340/68

b = 5

Insert the value of b in equation (ii)

a + 10b = 59.75.......(ii)

a + 10 × 5 = 59.75

a = 59.75 - 50

a = 9.75

price of each bags of popcorn = $9.75

price of each drinks = $5

masya89 [10]

Answer:

C' (-4 , 2)

slope of new line = line "L" = -2

Step-by-step explanation:

C (x₀,y₀): (0,2)    dilation center (h,k): (2,2)     scale factor (sf): 3

C' (x,y)

x = 2 + 3*(0-2) = -4            x = h + sf*(x₀ - h)

y = 2 + 3*(2-2) = 2             y = k + sf*(y₀ - k)

C' (-4 , 2)

slope of new line = line "L" = -2
