Answer:

x ≥ -4

Step-by-step explanation:

-8x + 4 ≤ 36

Subtract 4 from both sides.

-8x ≤ 32

Divide both sides by -8. Remember to flip the inequality sign when dividing or multiplying by a negative number.

x ≥ -4

Ket [755]

<O = 16 degrees vertical angles are equal

<O + 4x+90 = 180 DC is a straight line

16 +4x +90 = 180

106 +4x = 180

4x =74

x =18.5

16 +90 +2y= 180 DC is a straight line

106+2y=180

2y = 74

y= 37

Answer : y=37

x=18.5

Ms. Peters drove from her home to the park

worty [1.4K]

It takes 15 minutes for Ms. Peter to drive from park to her home

Given :

from her home to the park at an average speed of 30 miles per hour and

returned home along the same route at an average speed of 40 miles per hour

it takes 20 minutes to travel

Convert 20 minutes in to hour (divide by 60)

20 minutes = 1/3 hour

We know that distance = speed x time

From home to park, distance = $speed \cdot time =30 \cdot \frac{1}{3} =10 miles$

So , distance between home and park is 10 miles

Now we calculate the time taken to return from park to home

$time taken =\frac{distance}{speed} =\frac{10}{40}=\frac{1}{4}\\$

Time taken is 1/4 hours. Convert it into minutes by multiplying by 60

$\frac{1}{4} \cdot 60=15$

So it takes 15 minutes for Ms. Peter to drive from park to her home

Answer:Do you have a pic of the map? It would make it easier to solve if I could see the map. Its basic area. A=base times height. If the park is 50 m long and is a square, you would do 50 times 50=2500
