Answer 1

Ответ:

2 и 1,78

Объяснение:

Х+3<5

Х=5>3

Х=2

Ответ:2

7(х+10)+22,5

7умножить(х+10)=22,5

7умножить(22,5-10)=х

7умножитьх=12,5

Х=12,5:7

Х=1,78

Ответ:1,78

Answer 2

It looks like you've provided two mathematical expressions. Let's break them down and solve for the variable "x" in each expression:

1. $x + 3 < 5$:

Subtract 3 from both sides of the inequality to isolate "x": $x + 3 - 3 < 5 - 3$ $x < 2$

So, the solution for this inequality is $x < 2$.

2. $7(x + 10) + 2 \leq 5$:

Distribute the 7 on the left side of the inequality: $7x + 70 + 2 \leq 5$

Combine the constants on the left side: $7x + 72 \leq 5$

Subtract 72 from both sides of the inequality: $7x \leq -67$

Finally, divide both sides by 7 (since the coefficient of x is 7) to solve for "x": $x \leq -\frac{67}{7}$

So, the solution for this inequality is $x \leq -\frac{67}{7}$.

Note that the second expression has been corrected based on what appears to be a formatting error. If you meant something different, please provide the correct expression, and I'll be happy to help you solve it.
