Answer 1

1) x=7,5

2)y=0,7

3)z=600

4)x=2,5

Answer 2

Ответ:

Пошаговое объяснение:

1) х:1,5=35:7 x=1,5*35/7=7,5

Х=5*1,5

Х=7,5

2) 9,1:у=65:5 y=9,1*5/65=0.7

У=9,1:13

У=0,7

3) 40:0,2= z:3 z= 40*3/0,2=600

Z:3=200

Z=200*3

Z=600

4) 54:2,7=50:x x=2,7*50/54=2,5

50:x=20

X=50:20

X=2,5

Answer 3

To solve these equations, we need to find the value of the unknown variables (x, y, and z). Let's go through each equation step by step:

1. х:1.5 = 35:7

To find the value of x, we can cross-multiply:

7 * x = 35 * 1.5

Now, solve for x:

7x = 52.5

x = 52.5 / 7

x ≈ 7.5

So, the value of x is approximately 7.5.

2. 9.1 : у = 65 : 5

To find the value of y, we can cross-multiply:

5 * 9.1 = 65 * y

Now, solve for y:

45.5 = 65y

y = 45.5 / 65

y ≈ 0.7

So, the value of y is approximately 0.7.

3. 40 : 0.2 = z : 3

To find the value of z, we can cross-multiply:

3 * 40 = 0.2 * z

Now, solve for z:

120 = 0.2z

z = 120 / 0.2

z = 600

So, the value of z is 600.

4. 54 : 2.7 = 50 : x

To find the value of x, we can cross-multiply:

2.7 * 50 = 54 * x

Now, solve for x:

135 = 54x

x = 135 / 54

x ≈ 2.5

So, the value of x is approximately 2.5.
