Answer:
Step-by-step explanation:For the student to be considered for the tutoring or extension activities, his/her score must be 20 points lower or higher than the average.
The average is given as 105, that means:
Minimum score to be considered = 105 - 20 = 85
Maximum score to be considered = 105 + 20 = 125
If p represents the performance of a student, then this inequality will be represented as follows:
85 ≤ p ≤125
Step-by-step explanation:
x=54
use pyth then the other line = 15
then 15÷90 = 9÷x
then x = 54
The first step would be to add 7 to both sides.
3n-7=30
add 7
3n=37
divide by 3
n=12.33
Answer: fax 2 F (y axis) +4.5 =23x2=46
Step-by-step explanation:
Step-by-step explanation:
<u>For the first one</u>,
2x < 10
- Divide both sides of the inequality by 2,
2x ÷ 2 < 10 ÷ 2
x < 5
<u>Now, for the second one</u>,
x/2 > 3
- Multiply both sides of the inequality by 2,
x/2 × 2 > 3 × 2
this will <em>cancel</em> the <em>fraction</em> and will give us,
x > 6
That's it! I hope this explanation was useful enough ;)
