Question

(2х+4):4 1/2=1 7/9:0,01​

Answer 1

Ответ:

18 80/81

Пошаговое объяснение:

(2х+4):4,5=1 7/9:0,01

9х+18=17/9:1/100

9х+18=1700/9

9х=1700/9-18

9х=1538/9

х=1538/81

х=18 80/81

Answer 3

Let's solve the expressions step by step:

1. (2x + 4) / 4.5: First, we simplify the expression in the parentheses: 2x + 4 Then, we divide the result by 4.5 So, the expression becomes: (2x + 4) / 4.5

2. 1 7/9 : 0.01: We convert the mixed number 1 7/9 into an improper fraction: 16/9 Then, we divide 16/9 by 0.01

Let's calculate each expression:

1. (2x + 4) / 4.5: This expression cannot be simplified further without knowing the value of 'x'. If you have a specific value for 'x', you can substitute it in to get a numerical result.

2. 16/9 : 0.01: To divide by a decimal, we can multiply by its reciprocal. The reciprocal of 0.01 is 100. So, (16/9) * 100 = 177.777...

Please note that the first expression still depends on the value of 'x' to be fully evaluated, and the second expression results in a decimal approximation.
