6) Solve for x. 2/3 (x + 7) = 10 <br><br> A)22 <br><br> B)8 <br><br> C)- 1 /3 <br><br> D)41/ 3
Amiraneli [1.4K]

For this case we must find the value of the variable "x" of the following equation:

\frac {2} {3} (x + 7) = 10

We multiply by 3 on both sides of the equation:

2 (x + 7) = 30

We divide between 2 on both sides of the equation:

(x + 7) = 15\\x + 7 = 15

We subtract 7 on both sides of the equation:

x = 8

Option B

Toby bought 8 hotdogs and 5 fries. It cost $34.00
ruslelena [56]

Answer:

Each hot dog = $3

Each french fry = $2

Step-by-step explanation:

First, lets define our variables:

x = Hotdog

y = fries

Next, you need to set up a cost equation for both Toby and Bernie:

8x + 5y = 34

2x + 6y = 18

Now, we need to isolate one of the variable:

2x + 6y = 18

2x = 18 - 6y

x = 9 - 3y

Next, we need to insert this equation back into the first equation (8x+5y = 34) to find the cost of y (fries):

8x +5y = 34

8 (9-3y) + 5y = 34

72 - 24y + 5y = 34

72 - 19y = 34

19y = 38

y or fries = $2

Finally, we need to find the cost of each hotdog by using the cost of fries ($2) in one of the formulas:

2x + 6y = 18

2x + 6(2) = 18

2x + 12 = 18

2x = 6

x or hotdog = $3

I hope this helps!
