PLEASE HELP ASAP 25 PTS + BRAINLIEST TO RIGHT/BEST ANSWER

MAVERICK [17]

Answer:

(-2,-5)

Step-by-step explanation:

y = 2x-1

3x-y = -1

We can use substitution

3x - (2x-1) = -1

Distribute the minus sign

3x -2x+1 = -1

x +1 =-1

Subtract 1 from each side

x+1-1 = -1-1

x=-2

Now we need to find y

y = 2x-1

y = 2(-2) -1

y = -4-1

y = -5

(-2,-5)

A sidewalk around a circular park covers a distance of 65 meters. A new sidewalk is being constructed across the park through it

lidiya [134]

All we have to do is divide the distance of the old sidewalk by 3.14:

65 / 3.14 ≈ 20.7006

That means that, rounded to the nearest meter, the new sidewalk is:

21 meters long!

I need help with this<br><br> 1. Find the area and<br> perimeter of the<br> shape. Show work.

balu736 [363]

Answer:

Area= 28.274 $cm^{2}$

Perimeter= 21.425 cm

Step-by-step explanation:

This is a quadrant.

Formula for area of a quadrant= $\frac{1}{4} *\pi r^{2}$

Area= $1/4\pi *6^{2}$

Area= 28.274 $cm^{2}$

Formula for perimeter of a quadrant= $0.5\pi r+2r$

r=6cm

Perimeter= $0.5\pi*6 +(2*6)$

Perimeter= 21.425 cm
