Y’all someone help pls 5x-3=21-x

attashe74 [19]

5x-3=21-x
6x=24
X=4

You simply have to isolate the variable and then divide by 6 so that x is completely alone.

A sector with a radius of 8 cm has an area of 56pi cm2. What is the central angle measure of the sector in radians?

Maurinko [17]

Answer:

$\frac{7\pi}{4}$ .

Step-by-step explanation:

Given information:

Radius of circle = 8 cm

Area of sector = $56\pi\text{ cm}^2$

Formula for area of sector is

$A=\dfrac{1}{2}\theta r^2$

where, r is radius and $\theta$ is central angle in radian.

Substitute $A=56\pi$ and r=8 in the above formula.

$56\pi=\dfrac{1}{2}\theta (8)^2$

$56\pi=\dfrac{64}{2}\theta$

$56\pi=32\theta$

$\dfrac{56\pi}{32}=\theta$

$\dfrac{7\pi}{4}=\theta$

Therefore, the measure of the sector in radians is $\frac{7\pi}{4}$ .

How do i solve this problem? how did they get 2.5?

WARRIOR [948]

Take the GCF (-8t) of the given expression.

You'll get -8t(2t-5).

Now, set each equal to zero and solve for x.

-8t = 0 2t-5=0

t=0 t = 5/2 (Or 2.5 seconds)
