Step-by-step explanation:

The circumference of a circle is equal to 2πr, where r is the radius.

2π(4) = 8π ≈ 25.132

The area of a circle is equal to πr²

In the equation 5x-2=-x-20, What is the value of x?<br> a. 2<br> b. -1<br> c. -3<br> d. -2

mestny [16]

Answer:

C choice.

Step-by-step explanation:

$5x - 2 = - x - 20 \\$

First, we move the same terms to the same side.

$5x + x = - 20 + 2 \\ 6x = - 18$

Then we move 6 to divide - 18.

$x = \frac{ - 18}{6} \\ x = - 3$

rjkz [21]

$2.25y + 7.25z + 11.25 \geq 35 \\ y = 2 \\ z = 3 \\ 2.25(2) + 7.25(3) + 11.25 \geq 35 \\ 4.50 + 21.75 + 11.25 \geq 35 \\ 37.5 \geq 35$
The answer will be the third one: Yes, because the total will be $37.50.
