Question

4 1/5 : 1 1/5 = 2 3/4 * 4 - 1 7/18x

Answer 1

Ответ:

Пошаговое объяснение:

4 1/5 : 1 1/5 = 2 3/4 * 4 - 1 7/18x

21/5*5/6=11/4*4-1 7/18x

7/2=11-1 7/18x

-1 7/18x=11-7/2

-1 7/18x=11-3.5

-25/18x=7.5

x=7.5:(-25/18)

x=15/2*(-18/25)

x=-27/5=-5.4

Answer 2

Ответ:

77/1800

Пошаговое объяснение:

...

4 1/5:11/5=2 3/4*4-1 7/18х

21/5*5/11=11/4*4-7/18х

21*1/11=11-7/18х

21/11=11-7/18х

7/18х=11-21/11

7/18х=100/11

77=1800х

1800х=77

х=77/1800

Answer 3

To solve the equation, let's simplify each side step by step:

4 1/5 : 1 1/5 To divide fractions, we need to convert them to improper fractions: 4 1/5 = (5 * 4 + 1)/5 = 21/5 1 1/5 = (5 * 1 + 1)/5 = 6/5

Now we can divide the fractions: (21/5) / (6/5) = (21/5) * (5/6) = (21 * 5) / (5 * 6) = 105/30

Next, let's simplify the other side of the equation:

2 3/4 * 4 - 1 7/18x 2 3/4 = (4 * 2 + 3)/4 = 11/4 1 7/18 = (18 * 1 + 7)/18 = 25/18

Now we can substitute the values and simplify further: (11/4) * 4 - (1 7/18)x = (11 * 4)/4 - (25/18)x = 11 - (25/18)x

Now, we have: 105/30 = 11 - (25/18)x

To solve for x, we'll isolate the variable on one side:

105/30 = 11 - (25/18)x

First, let's simplify the fraction 105/30: 105/30 = 3.5

Now we have: 3.5 = 11 - (25/18)x

To isolate x, we can subtract 11 from both sides: 3.5 - 11 = -7.5 = - (25/18)x

To get rid of the negative sign, we'll multiply both sides by -1: 7.5 = (25/18)x

Now, to solve for x, we'll multiply both sides by the reciprocal of (25/18), which is (18/25):

(18/25) * 7.5 = x

0.72 = x

Therefore, the solution to the equation is x = 0.72.
