3x-y=13
step 1: add y to both sides
3x-y+Y=13+Y
3x=y+13
step 2: divide both sides by 3
3x/ 3 = y+13/3
x=1/3y+ 13/3
answer: x=1/3y+13/3
Answer:
answer a because -15/8 is -1.875
Answer:
7.3≤x<7.4
Step-by-step explanation:
<u>Answer:</u>
x = 14° || each angle has 108°
<u>explanation:</u>
first we need to find the total interior angle of this shape:
formula: ( n - 2 ) * 180 ..............where n is the number of sides
( 5 -2 ) * 180
540°
if all sides in the shape are equal, they must have same angle of 9x -18
5 ( 9x -18 ) = 540°
9x -18° = 108°
9x = 108° + 18°
9x = 126°
x = 14°
So each angle has: 9x - 18
9(14) - 18
108°
Area of the square = Length x Length
Area of the square = 12 x 12
