Answer 1

Ответ:

27,5

Пошаговое объяснение:

5,7+4.3+3.9+2.9+3.7+2.3+2.9+1.8 = 10 + 3.9+2.9+3.7+2.3+2.9+1.8 = 13,9 + 2.9+3.7+2.3+2.9+1.8 = 16,8 + 3.7+2.3+2.9+1.8 = 20,5 + 2.3+2.9+1.8 = 22,8 +2.9+1.8 = 25,7 + 1,8 = 27,5

Answer 2

To solve for the missing number in the equation:

(5 + 7 + 4.3 + 3.9 + 2.9 + 3.7 + 2.3 + 2.9 + 1.8) / x = 8

You can first add up all the numbers on the left side of the equation:

5 + 7 + 4.3 + 3.9 + 2.9 + 3.7 + 2.3 + 2.9 + 1.8 = 34.8

Now, you have:

34.8 / x = 8

To solve for x, you can isolate x by multiplying both sides of the equation by x:

34.8 = 8x

Now, divide both sides by 8 to solve for x:

x = 34.8 / 8

x = 4.35

So, the missing number x is equal to 4.35, making the equation true:

(5 + 7 + 4.3 + 3.9 + 2.9 + 3.7 + 2.3 + 2.9 + 1.8) / 4.35 = 8
