If x is a factor of y and y is a factor z, then x is a factor of z. true or false

True; this would indeed be a factor of .

Step-by-step explanation:

" is a factor of " means that there is a whole number such that .

Likewise, is a factor of if and only if there is a whole number such that .

This would be a factor of if there is some whole number such that .

The first equality implies that may be substituted with .

Substitute the in the second equality with to obtain:

.

Rearrange to obtain:

.

The product of two whole numbers is still a whole number. Since and are both whole numbers, would also be a whole number.

Thus, if , then , while would be a whole number.

Therefore, this would indeed be a factor of .

step-by-step explanation:

do 6-10=

if u need it to be negative.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
