4x=5(2x-5)\\
4x=10x-25\\
6x=25\\
x=\frac{25}{6}\\\\
y=2\cdot\frac{25}{6}-5\\
y=\frac{25}{3}-\frac{15}{3}\\

Area and circumference of this circle
faust18 [17]

Answer:

Step-by-step explanation:

Given: The radius is 6 cm

To find the area + circumference we need to use 2 formulas:

Area: pi* radius^2

Circumference: 2*pi*r

First we can do the area

I will use "pi" for pi instead of 3.14

pi * 6^2

= 36 pi

The area is 36 pi

Next, circumference

2 * pi *r

2*pi*6

= 12 pi

So the area is 36 pi, and the circumference is 12 pi

-4-3 (6x + 9) = 41?<br> Explain what to do first and what is the answer
lara31 [8.8K]

Answer:

x = -2

Step-by-step explanation:

9 - 4 = 5

- 18x + 5 = 41

- 18x = 41 - 5

- 18x = 36

36 divided by -18 is -2
