Question

В)3,6X +1,7 X=40,28г) 11,6k-2, 48=2, 16

Answer 1

в) 3,6х + 1,7х= 40,28

5,3х=40,28

х=40,28/5,3

х=7,6

г) 11,6к-2,48=2,16

11,6к=2,16+2,48

11,6к=4,64

к=4,64/11,6

к=0,4

Answer 2

To solve the equations, we'll need to isolate the variable "X" in the first equation and "k" in the second equation. Let's start with the first equation:

1. 3.6X + 1.7X = 40.28

Combine the X terms:

5.3X = 40.28

Now, isolate X by dividing both sides by 5.3:

X = 40.28 / 5.3 X ≈ 7.5877

So, the value of X is approximately 7.5877.

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

2. 11.6k - 2.48 = 2.16

Add 2.48 to both sides to isolate the term with k:

11.6k = 2.16 + 2.48 11.6k = 4.64

Now, isolate k by dividing both sides by 11.6:

k = 4.64 / 11.6 k ≈ 0.4

So, the value of k is approximately 0.4.
