Question

(180:a+15*3):8=6Help me pleaseplease​

Answer 1

Ответ:

а=60

Пошаговое объяснение:

(180:a+15*3):8 = 6

(180:а+45) = 6*8

180:а+45 = 48

180:а = 48-45

180:а = 3

а = 180 :3

а = 60

Проверка (подставим а=60)

(180:60 + 15*3) :8 = 6

6 = 6

Answer 2

To solve the equation (180 + a + 15 * 3) / 8 = 6, we can follow the order of operations (PEMDAS/BODMAS):

1. First, simplify the expression inside the parentheses: 180 + a + 15 * 3 = 180 + a + 45 = 225 + a

2. Rewrite the equation with the simplified expression: (225 + a) / 8 = 6

3. To isolate the variable 'a', we can multiply both sides of the equation by 8: 8 * (225 + a) / 8 = 6 * 8

   Simplifying, we get: 225 + a = 48

4. Next, we need to isolate 'a'. To do that, subtract 225 from both sides: 225 + a - 225 = 48 - 225

   Simplifying, we get: a = -177

Therefore, the solution to the equation is a = -177.
