x ≥-5

Step-by-step explanation:

- 3x + 2≤ 17

Subtract 2 from each side

- 3x + 2 -2 ≤ 17-2

-3x ≤15

Divide each side by -3, remembering to flip the inequality

-3x/-3 ≥15/-3

x ≥-5

the first sentence of this question, can be mathematically expressed as follows:

$l+25\%l=m$ (1)

where $l$ represents the bugs the spider ate last month, and $m$ represents the bugs the spider ate this month.

also, we know the spider ate 8 bugs last month, which can be represented by the equation below:

$l=8$ (2)

well, in order to find the bugs the spider ate this month ( $m$ ), we have to substitute (2) in (1), because we already know the value of $l$ :

$8+25\%(8)=m$

notice that $25\%$ is $\frac{25}{100}$

$8+\frac{25}{100}(8)=m$

$8+2=m$

finally:

$m=10$

this means the spider ate 10 bugs this month
