Please, when you present a list of numbers, such as 4, 8, 16, ..., separate them with commas or semicolons: 4, 8, 16, ...

If x^2 + y^2 = 16, then 16 represents r^2, and r = 4. r cannot be negative in this type of problem.

Which expression is equivalent to. 3( x+6)

nata0808 [166]

I think the answer is 3x + 18 because:

3 * x = 3x
and
3 * 6 = 18

That equals 3x + 18.

Hope this helped☺☺

The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?

Anestetic [448]

Answer:

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Step-by-step explanation:

Let

x -----> represent the measures of the seven same-size angles,

x/2 ----> represent the measure of the one that is "two times smaller."

we know that

The sum of internal angles of a polygon can be calculated as:

$S=180^o(n-2)$

where

n is the number of sides of the polygon

In this case

n=8 (octagon)

substitute

$S=180^o(8-2)=1,080^o$

The linear equation that represent this problem is

$\frac{x}{2}+7x=1,080$

solve for x

$\frac{15x}{2}=1,080\\\\15x=2,160\\\\x=144^o$

$\frac{x}{2}=72^o$

therefore

7 of the angles measure 144 degrees each and one angle measures 72 degrees

5 kilograms of coffee are going to be shared equally among 4 people.

kherson [118]

Step-by-step explanation:

I'm not sure if this will help but to find out how much coffee 4 people would need you would have to divide 4 into 5 which is 1 1/5

EQUATION-- 4/5= X

I chose that because / means divide 5 into 4 would give you x we don't know what x is until we actually do the problem

Even if im not correct I hope it helped a bit
