Question

64÷х=32х+580=74030×х=270​

Answer 1

Ответ:

64:x=32

x=64:32

64:32=2

x=2

x+580=740

x=740-580

740-580=160

x=160

30×x=270

x=270:30

270:30=9

x=9

Answer 2

Ответ:

1) x = 2

2) x = 160

3) x = 9

Пошаговое объяснение:

64 / x = 32

x = 64 / 32

x = 2

x + 580 = 740

x = 740 - 580

x = 160

30 * x = 270

x = 270 / 30

x = 9

Answer 3

It appears that you have three equations involving the variable "x." Let's solve them step by step:

1. 64/x = 32x + 580
2. 74030x = 270

Let's start with the first equation:

1. 64/x = 32x + 580

To solve for x, you can first multiply both sides of the equation by x to eliminate the fraction:

64 = 32x^2 + 580x

Now, rearrange the equation:

32x^2 + 580x - 64 = 0

You now have a quadratic equation. To solve for x, you can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this case, a = 32, b = 580, and c = -64. Plugging these values into the formula:

x = (-580 ± √(580^2 - 4 * 32 * (-64))) / (2 * 32)

x = (-580 ± √(336400 - (-8192))) / 64

x = (-580 ± √(344592)) / 64

x = (-580 ± 588) / 64

Now, you can find two solutions:

1. x = (-580 + 588) / 64 = 8/64 = 1/8
2. x = (-580 - 588) / 64 = -1168/64 = -23/2

Now, let's move on to the second equation:

2. 74030x = 270

To solve for x in this equation, divide both sides by 74030:

x = 270 / 74030

x = 0.003647

So, the solutions for the three equations are:

1. x = 1/8
2. x = -23/2
3. x = 0.003647
