Question

9z-8,5z=2,7855 (t+0,1)×1,5=35,004

Answer 1

Ответ:

0.5z=2.7855

z=2,7855:0,5

z=5,571

1,5t+0,15=35,004

1,5t=34,854

t=34,854:1,5

t=23,236

Answer 2

To solve the equations, let's first handle each equation step by step:

1. 9z - 8 - 5z = 2.7855

Combine like terms:

(9z - 5z) - 8 = 2.7855

4z - 8 = 2.7855

Add 8 to both sides to isolate the term with z:

4z = 2.7855 + 8

4z = 10.7855

Now, divide both sides by 4 to solve for z:

z = 10.7855 / 4

z ≈ 2.6964

So, the value of z is approximately 2.6964.

2. (t + 0.1) × 1.5 = 35.004

Distribute the 1.5 on the left side of the equation:

1.5t + 1.5(0.1) = 35.004

1.5t + 0.15 = 35.004

Now, subtract 0.15 from both sides to isolate the term with t:

1.5t = 35.004 - 0.15

1.5t = 34.854

Finally, divide both sides by 1.5 to solve for t:

t = 34.854 / 1.5

t ≈ 23.236

So, the value of t is approximately 23.236.
