Пошаговое объяснение:

3х+5х=64

8х=64

х=8

3х=3*8=24

5х=5*8=40

7х+12х=114

19х=114

х=6

7х=7*6=42

5х=5*25=125

7х=7*25=175

9х=9*25=225

Answer 2

Breaking down numbers in different ratios

To break down a number in a specific ratio, we need to divide the number into parts according to the given ratio. Let's break down the numbers you provided:

1. Breaking down 64 in the ratio 3:52: To break down 64 in the ratio 3:52, we need to divide it into two parts. To find the values of these parts, we can use the concept of proportion.

Let's assume the two parts are x and y. According to the given ratio, we have the equation:

3/52 = x/64

To solve for x, we can cross-multiply and get:

3 * 64 = 52 * x x = (3 * 64) / 52 x ≈ 3.692

Therefore, the two parts are approximately 3.692 and 60.308.

2. Breaking down 114 in the ratio 7:123: To break down 114 in the ratio 7:123, we need to divide it into two parts. Using the same concept of proportion, we can set up the equation:

7/123 = x/114

Cross-multiplying, we get:

7 * 114 = 123 * x x = (7 * 114) / 123 x ≈ 6.465

So, the two parts are approximately 6.465 and 107.535.

3. Breaking down 70 in the ratio 3:6;8:114: To break down 70 in the ratio 3:6;8:114, we need to divide it into three parts. Let's assume the three parts are x, y, and z. Using the concept of proportion, we can set up the equations:

3/6 = x/70 8/114 = y/70

Solving for x and y, we get:

x = (3 * 70) / 6 x = 35

y = (8 * 70) / 114 y ≈ 4.912

To find z, we subtract the sum of x and y from 70: z = 70 - (x + y) z = 70 - (35 + 4.912) z ≈ 29.088

Therefore, the three parts are approximately 35, 4.912, and 29.088.

4. Breaking down 525 in the ratio 5:7:9: To break down 525 in the ratio 5:7:9, we need to divide it into three parts. Let's assume the three parts are x, y, and z. Using the concept of proportion, we can set up the equations:

5/7 = x/525 9/525 = z/525

Solving for x and z, we get:

x = (5 * 525) / 7 x ≈ 375

z = (9 * 525) / 525 z = 9

To find y, we subtract the sum of x and z from 525: y = 525 - (x + z) y = 525 - (375 + 9) y = 141

Therefore, the three parts are 375, 141, and 9.
