Answer:
x is the missing side (x > 0)
because this is a right triangle, using Pythago theorem, we have:
x² + 4² = 12²
⇔ x² = 12² - 4²
⇔ x² = 128
=> x ≈ 11.3
Step-by-step explanation:
Collect like terms.
8x - 2 + x = 14
9x - 2 = 14
9x = 16
1/6 can be be 4/24, 1/3 can be 8/24, and 1/4 can be 6/24. Add them together and you get 18/24, then do 1 (or 24/24) minus 18/24 which equals 6/24 or 1/4
You need 10 logs for 1 brick. To get 10 bricks you need 100 logs. You are collecting stones and 1 stone gets you 4 logs. That means to get 100 logs you’ll need 25 stones. That indirectly means that 25 stones gets you 10 bricks.
