Answer:

x = 1

Step-by-step explanation:

Step 1: Combine like terms.

$(29x + x) = (30)$
$30x=30$

Step 2: Divide both sides by 30.

$30x/30=30/30$
$x=1$

Step 3: Check if solution is correct.

$29(1)+(1)=30$
$29+1=30$
$30=30$

Therefore, x = 1.

3. What is the radius of the figure if the Area of the Sector is 288*pi? *

Alla [95]

Answer:

The radius of the circle is 36

x = 36

Step-by-step explanation:

Area of sector formula is:

$A=\frac{\theta}{360}*\pi r^2$

Given $\theta=80$ , and area (A) is $288\pi$ , we substitute and solve for r:

$A=\frac{\theta}{360}*\pi r^2\\288\pi=\frac{80}{360}*\pi r^2\\288\pi=\frac{2}{9}*\pi r^2\\288\pi=\frac{2\pi r^2}{9}\\2\pi r^2= 2592 \pi \\r^2= 1296\\r=\sqrt{1296}\\r=36$

Thus,

The radius of the circle is 36

x = 36

Simplify the expression. 68 – 18 ÷ 3 • 6 Please help

MAXImum [283]

Remember PEMDAS (Parenthesis, Exponents, Multiplication, Divison, Addition and Subtraction)

Also note that Multiplication and Division needs to be done left to right and the same goes for Addition and Subtraction.

So in your problem, the first operation we need to do is division.

68 - (18/3) x 6
68 - 6 x 6

Now we do multiplication
68 - 6 x 6
68 - 36

Finally we do subtraction because that's the only operation we have left to do
68 - 36 = 32

So your answer should be 32.
