Question

Рiвня a:6=42:6 54-y=54-17 8.k=8.4​

Answer 1

a:6=42:6

a:6=7

а=7*6

а=42

54-y=54-17

54-у=37

у=54-37

у=17

8*k=8*4

8*k=32

k=32:8

k=4

Answer 2

To solve these equations, let's go through each one:

1. Рiвня a: 6 = 42:6 This equation states that the quotient of 42 divided by 6 is equal to 6. We can verify this by performing the division: 42 divided by 6 is indeed 7. Therefore, the equation is not true as stated.

2. 54-y = 54-17 This equation states that the difference between 54 and y is equal to the difference between 54 and 17. To solve for y, we can subtract 54 from both sides of the equation: 54 - 54 - y = 54 - 17 - 54 0 - y = -17 -y = -17 To isolate y, we can multiply both sides by -1: (-1)(-y) = (-1)(-17) y = 17 Therefore, the solution to this equation is y = 17.

3. 8.k = 8.4 It seems that the variable k is written with a dot between the number 8 and k. If we interpret this as a decimal point, we can rewrite the equation as: 8k = 8.4 To solve for k, we divide both sides by 8: (8k)/8 = 8.4/8 k = 1.05 Therefore, the solution to this equation is k = 1.05.

In summary:

1. The equation Рiвня a:6=42:6 is not true as stated.
2. The solution to the equation 54-y = 54-17 is y = 17.
3. The solution to the equation 8.k = 8.4 is k = 1.05.
