3(x-2)+7=19 I’m sorry can some one please help me I just don’t get it

x=6

Step-by-step explanation:

3(x-2)+7=19

distribute the 3 through the parentheses:

3x-6+7=19

Simplify:

3x+1=19

Move the constant (1) to the right-hand side and change its sign

3x=19-1

Subtract the numbers:

3x=18

Divide both sides by 3 to get x alone:

x=6

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
