Question

1.3 = 4 * (k + 2) 5 * ( c +5) = -7

Answer 1

1.3 = 4 * (k + 2);

1.3 = 4k + 8;

-4k=6,7;

k=-1,675;

5 * ( c +5) = -7;

5c+25=-7;

5c=-7-25;

c=-6,4

Answer 2

To solve the equations, let's first focus on each equation separately.

1. 1.3 = 4 * (k + 2)

To solve for 'k', follow these steps:

Step 1: Distribute the 4 on the right side of the equation. 1.3 = 4k + 8

Step 2: Isolate 'k' on one side by subtracting 8 from both sides. 1.3 - 8 = 4k -6.7 = 4k

Step 3: Finally, divide both sides by 4 to find the value of 'k'. k = -6.7 / 4 k = -1.675

So, the value of 'k' is approximately -1.675.

2. 5 * (c + 5) = -7

To solve for 'c', follow these steps:

Step 1: Distribute the 5 on the left side of the equation. 5c + 25 = -7

Step 2: Isolate 'c' on one side by subtracting 25 from both sides. 5c = -7 - 25 5c = -32

Step 3: Finally, divide both sides by 5 to find the value of 'c'. c = -32 / 5 c = -6.4

So, the value of 'c' is -6.4.

Therefore, the solutions for the given equations are: k ≈ -1.675 c = -6.4
