Answer 1

16,5-(t+3,4)=4,9 t+3,4=16,5-4,9 t+3,4=11,6 t=11,6-3,4 t=8,2

Answer 2

Solving the Equations

1. 16.5 - (t + 3.4) = 4.9

To solve for t, we can start by isolating the variable t. First, let's simplify the equation:

16.5 - (t + 3.4) = 4.9 16.5 - t - 3.4 = 4.9 13.1 - t = 4.9

Now, we can isolate t by subtracting 13.1 from both sides:

13.1 - t = 4.9 -t = 4.9 - 13.1 -t = -8.2

Finally, we can solve for t by multiplying both sides by -1:

t = 8.2

So, the solution to the first equation is t = 8.2.

2. r + 16.23 - 15.8 = 7.1

To solve for r, we can start by isolating the variable r. First, let's simplify the equation:

r + 16.23 - 15.8 = 7.1 r + 0.43 = 7.1

Now, we can isolate r by subtracting 0.43 from both sides:

r + 0.43 = 7.1 r = 7.1 - 0.43 r = 6.67

So, the solution to the second equation is r = 6.67.
