Question

1,6×(3/8t-0.4z) -0,2×(3t+0, 64z) ​

Answer 1

Ответ:96/125z

Пошаговое объяснение:

8/5×(3/8t-2/5z)-0,6t-0,128z

3/5t-16/25z-3/5t-0,128z

-16/25z-16/125z

-96/125z

Answer 2

To simplify the given expression, follow these steps:

1. Distribute the coefficients to each term inside the parentheses.
2. Combine like terms (terms with the same variable and exponent).

Given expression: 1.6 × (3/8t - 0.4z) - 0.2 × (3t + 0.64z)

Step 1: Distribute the coefficients to each term inside the parentheses:

1.6 × 3/8t - 1.6 × 0.4z - 0.2 × 3t - 0.2 × 0.64z

Step 2: Combine like terms:

To combine terms with 't', we need to find the common terms (the ones with 't') and add or subtract them:

(1.6 × 3/8 - 0.2 × 3) t

To combine terms with 'z', we need to find the common terms (the ones with 'z') and add or subtract them:

(-1.6 × 0.4 - 0.2 × 0.64) z

Now, let's simplify the expressions inside the parentheses:

1.6 × 3/8 = 1.6 × 0.375 = 0.6 -0.2 × 3 = -0.6 -1.6 × 0.4 = -0.64 -0.2 × 0.64 = -0.128

Substitute these values back into the expression:

(0.6t - 0.6z) - (0.64t + 0.128z)

Now, combine the like terms again:

(0.6t - 0.64t) + (-0.6z - 0.128z)

Simplify further:

-0.04t - 0.728z

So, the simplified expression is -0.04t - 0.728z.
