Answer:

$3x+$5y=C and the total cost is $ 78

Step-by-step explanation:

the equation first is going to be  $3x+$5y=C

x: small balloons

y: large balloons

c: total cost

Now to find the how much the total cost is, you should substitute the variables  and then solve the equation.

x: 11

y:9

3(11)+5(9)= 33+45

two pounds of grapes cost $6 . complete the table showing the price of different amounts of grapes at this rate
Degger [83]

Answer:

Table shown below

Step-by-step explanation:

To solve this problem let's use proportions.

If 2 pounds of grapes cost $6, half the amount will cost half the dollars, so the last row will have $3 in the price

For the second row, we know the price is $1, that is, one-sixth of the original given price. It should correspond to one-sixth of the amount of grapes or 2/6 pounds.

Simplifying the fraction, we get 1/3 or 0.33 pounds

How do you find x and y from this diagram? I have no clue...
Montano1993 [528]

50 + (3x - y) = x + (2x - 16). Combine like terms to change the 2nd part to get 3x - 16. 50 + 3x-y = 3x - 16. Subtract 3x from both sides to get 50 - y = -16. Subtract 50 from both sides to get -y = - 66, or y = 66. 90 - 50 = 40 = 3x - 66. Add 66 to both sides to get 3x = 106, or x = 35 1/3.

It takes Joey 1/16 of an hour to write one Thank You card. How many cards can he write in 3/4 of an hour?
Naddik [55]
The answer would be 12 cards. If you convert 3/4 into 12/16, it tells you automatically that Joey made 12 cards, since it takes him 1/16 of an hour to write one.
Hope this helps!
