Answer:

c = -75/14 OR c = -5.357143

Step-by-step explanation:

Simplify both equations:

1.2x + 7 - 5x =

-3.8x + 7

2.2c - 3 = 2(6 - c) + 7c =

Whats the answer to 1/2(5×-8)=-9
REY [17]

Answer:

I do not know if that x is a multiply sign or a variable so I'm going to answer both

If the x is a multiplication sign then the answer is -20 = -9

If the x is a variable then the answer is x = -2

Step-by-step explanation:

1/2(5 * -8) = -9

(1 * 5 * -8)/2 = -9

(5 * -8)/2 = -9

-40/2 = -9

-20 = -9

-20 ≠ -9

1/2(5x - 8) = -9

1(5x -8)/2 = -9

(5x - 8)/2 = -9

2((5x - 8)/2) = -9 * 2

2(5x - 8)/2 = -9 * 2

5x - 8 = -9 * 2

5x - 8 = -18

    +8    +8

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

5x = -10

x = -10/5

x = -2

A local restaurant allows groups to rent out a party room in order to host events. The restaurant charges $600 to rent the room
OleMash [197]

Answer:

y = (10x + 600)/x

Step-by-step explanation:

To find the average cost, we must divide the total cost by the number of people.

The number of meals served will equal the number of people, since everybody gets just 1 meal.

Each meal is 10 dollars, plus the 600 rental fee.

The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.
