Question

2z+5>10z-17 при значение x равное 1.75 ​

Answer 1

2z +5>10z-17

2z-10z>-5-17

-8z>-22

z>-22/-8

z>2.75

Answer 2

It looks like there might be a mistake in the question. The inequality is written as 2z + 5 > 10z - 17, but then you mention "x" with a value of 1.75. I'll assume you meant "z" instead of "x" in the question.

To solve the inequality 2z + 5 > 10z - 17, follow these steps:

Step 1: Move the variable terms to one side of the inequality and the constant terms to the other side.

2z + 5 > 10z - 17

Subtract 2z from both sides:

2z - 2z + 5 > 10z - 2z - 17

Simplify:

5 > 8z - 17

Step 2: Isolate the variable term on one side by moving constant terms to the other side.

Add 17 to both sides:

5 + 17 > 8z - 17 + 17

Simplify:

22 > 8z

Step 3: Now, isolate "z" by dividing both sides by 8 (the coefficient of z).

22/8 > 8z/8

Simplify:

2.75 > z

So, the solution to the inequality when z = 1.75 is:

2.75 > 1.75

This statement is true, which means that the inequality 2z + 5 > 10z - 17 holds true when z = 1.75.
