5x + 3y = 22
y = 2x

Substitute y=2x into the first equation

5x + 3(2x) = 22
5x + 6x = 22
11x = 22
x = 2

Hope that helps :)

Brooke has to set up 70 chairs for the class talent show. But, there is not room for more than 20 rows.
den301095 [7]
If there are 70 chairs but only 20 rows then that means he will have to set up 3.5 chairs per row, or Brook could set up 14 rows with 5 chairs in each row.

Srry if that didn't help but that's what i got from that.

Here's a recipe for pancakes:
sweet [91]

Answer:

Milk: 1000 ml

Flour: 480 g

Butter: 250 g

Step-by-step explanation:

To calculate the amount of butter you have to figure out more flour she used.

First, 480 ÷ 120 = 4 So she uses 4 times the amount of flour.

Then, 60 × 4 = 240

Next, you need the amount of milk so we also multiply by 4.

250 × 4 = 1000

Lastly, have a great day!
