Question

5×(3×-7)+2(1-×) при =​

Answer 1

Ответ:

5*(3х-7)+2(1-х)=15х-35+2-2х(15х-2х)+(2-33)=13х-33, если х=1/26, то

13*1/26-33=0.5-33=-32.5

Объяснение:

Answer 2

Ответ:

- 32,5.

Объяснение:

$5(3x - 7) + 2(1 - x) = 15x - 35 + 2 - 2x = 13x - 33.$

При х = 1/26:

$13 \times \frac{1}{26} - 33 = \frac{1}{2} - 33 = 0.5 - 33 = - 32.5.$

Answer 3

It seems there might be some typographical errors in the expression you provided, making it a bit unclear. I assume you want to solve the expression, but there's a missing value for "×". I'll provide a solution with a placeholder for "×".

The expression you provided is:

5 × (3 × -7) + 2 × (1 - ×)

If you provide a specific value for "×," I can calculate the result for you. For example, if "×" is equal to 4, the expression would look like this:

5 × (3 × -7) + 2 × (1 - 4)

Now, let's solve it:

1. 3 × -7 = -21
2. 1 - 4 = -3

Now, plug these values into the expression:

5 × (-21) + 2 × (-3)

Now, calculate each part:

• 5 × (-21) = -105
• 2 × (-3) = -6

Now, add the results together:

-105 - 6 = -111

So, if "×" is 4, the result of the expression is -111. If "×" is a different value, please provide that value, and I can recalculate the expression for you.
