Answer:
Step-by-step explanation:
<h3>#18</h3>
Conditional statement p → q, and its inverse is not p → not q.
Applied to the given statement we see the correct one is b.
<h3>#19</h3>
Let the cost of fish is f.
<u>As per question we have:</u>
- 2(250) + 3f < 700
- 500 + 3f < 700
- 3f < 200
- f < 200/3 ≈ 67
The maximum cost is 66 pesos.
Correct choice is c.
<h3>#20</h3>
<u>Given function:</u>
The range is all real numbers as no restrictions to its domain.
Correct choice is c.
Answer: D
Step-by-step explanation:
If 30% failed then (100-30)% passed
That is 70%
let x be the number of students that wrote the exam
(70/100)x=210
x=21000/70
x=300
Answer:
see below.
Step-by-step explanation:
1st row has four small boxes
2nd row has three big boxes
big box 1 has no items ragged in it.
big box 2 has small box 1 and also small box 1 dragged into it.
big box 3 has small box 3 and small box 4 dragged into it.
3(m - 2) - 4>= 7m + 4
Use distributive property
3m - 6 - 4>= 7m + 4
Subtract 7m from both sides
-4m - 6 - 4>= 4
Add 6 to both sides
-4m - 4>= 10
Add 4 to both sides
-4m>= 14
Divide both sides by -4 so that the only thing remaining on the left side is the variable m.
Final Answer: m<= -14/4 or 3.5 or 3 1/2 *All the answers are equivalent to each other.
