Question

A) 1,6:* = 4,64. *6) 1,98 : (0,7 - x) = 4,5​

Answer 1

Ответ:

Пошаговое объяснение:

a) 1,6:0,34 = 4,64

1,6:4,64=0.34

6) 1,98 : (0,7 - x) = 4,5​

0,7-х=0,9

-х=0,2

х= -0,2

Answer 2

Ответ:

а)

1,6 : х = 4,64

х = 1,6 : 4,64

х = 1. 6/10 : 4. 64/100

х = 16/10 : 464/100

х = 16/10 * 100/464

х = 1/1 * 10/29

х = 10/29

б)

1,98 : (0,7 - х) = 4,5

0,7 - х = 1,98 : 4,5

0,7 - х = 0,44

х = 0,7 - 0,44

х = 0,26

Answer 3

It looks like you've provided two equations, and it appears that you want to solve for the variable "x" in the second equation. Let's solve each equation step by step:

A) 1,6 * x = 4,64

To solve for "x" in this equation, you can divide both sides by 1.6:

x = 4.64 / 1.6 x = 2.9

So, in the first equation, x is equal to 2.9.

B) 1.98 / (0.7 - x) = 4.5

Now, let's solve for "x" in the second equation:

First, subtract 0.7 from both sides:

1.98 / (0.7 - x) - 4.5 = 0

Now, we can solve for x. To isolate x in the denominator, you can multiply both sides of the equation by (0.7 - x):

1.98 - 4.5(0.7 - x) = 0

Now, distribute the 4.5 on the left side:

1.98 - 3.15 + 4.5x = 0

Combine like terms:

4.5x = 3.15 - 1.98 4.5x = 1.17

Now, divide by 4.5 to solve for x:

x = 1.17 / 4.5 x = 0.26

So, in the second equation, x is equal to 0.26.

To summarize: A) In the first equation, x = 2.9. B) In the second equation, x = 0.26.
