Answer:

18) b, 19) c, 20) c

Step-by-step explanation:

Conditional statement p → q, and its inverse is not p → not q.

Applied to the given statement we see the correct one is b.

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.

<u>Given function:</u>

y = √3 - s

The range is all real numbers as no restrictions to its domain.

3xy^3+5-x-2xy^3=xy^3+11

Viktor [21]

Answer: x=-6

Sorry, I am only able to find the x :(

Step-by-step explanation:

Step 1: Add -xy^3 to both sides.

$xy^3-x+5+-xy^3=xy^3=xy^3+11+-xy^3$

$-x+5=11$

Step 2: Add -5 to both sides.

$-x+5+-5=11+-5\\-x=6$

Step 3: Divide both sides by -1.

$\frac{-x}{-1} =\frac{6}{-1}$

A building in a city has a rectangular base. The length of the base measures 75 ft less than twice the width The perimeter of th

Oliga [24]

Answer:

Width: 255 feet

Length: 180

Step-by-step explanation:

Hi there!

Perimeter = 2 × width + 2 × length

Let w be equal to the length of the base

Plug in the given information:

870 = 2 × w + 2 × (w-75)

870 = 2w+2w-150

870 = 4w-150

4w=1020

w=255

Therefore, the width of the base is 255 ft.

To find the length of the base, subtract 75 from 255:

255-75 = 180

I hope this helps!
