Answer:

Relationship between c and f is 7c - 3f = 0

Step-by-step explanation:

Since Clare has to use 9 cups each of them having 1/3 part filled with flour for making of 4 cakes.

Implies that 4 cakes require 28/3 cups of flour.

So 1 cake will require 28/4 x 3 cups of flour.

And c cakes will require 28c/12 cups of flour.

Hence according to the question

28c/12 = f

⇒ 28c = 12f

⇒ 7c = 3f

⇒ 7c - 3f = 0 is required equation.

Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total t
Ilia_Sergeevich [38]

Answer: 220

<u>Step-by-step explanation:</u>

Children (x): $2

Teens (y): $3, \frac{3}{4}x

Adults: (z): $5

Quantity: x + y + z = 570  ⇒  x + \frac{3}{4}x + z = 570  ⇒ 1.75x + z = 570  

Cost: 2x + 3y + 5z = 1950  ⇒  2x + 3(\frac{3}{4}x) + 5z = 1950  ⇒  2x + 2.25x + 5z = 1950  ⇒  4.25x + 5z = 1950

Qty:    1.75x +  z =  570  →  5(1.75x +  z =  570)  →    8.75x + 5z = 2850

Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → <u> -4.25x - 5z</u> = <u>-1950 </u>

                                                                                  4.50x        =   900

                                                                                          x       =    200

Teens (y): \frac{3}{4}x

           y = \frac{3}{4}(200)

             = \frac{600}{4}

             = 150

Quantity: x + y + z = 570  

              200 + 150 + z = 570

                     350     + z = 570

                                    z = 220

Help me please with math
koban [17]

Answer:

2) y = x - 4

   y = -x + 2

   => x - 4 = -x + 2

   => 2x = -6

   => x = -3

   => y = -3 - 4 = -7

3) y = 3x + 1

   y = 5x - 3

   => 3x + 1 = 5x - 3

   => 2x = 4

   => x = 2

   => y = 3(2) + 1 = 7

4) 2x + y = 8 => y = -2x + 8

   y = x - 7

   => -2x + 8 = x - 7

   => 3x = 15

   => x = 5

   => y = 5 - 7 = -2
