Answer:
y = 3
Step-by-step explanation:
(5y - 3)/4 + 6 = 3y
5y - 3 + 24 = 12y
7y = 21
y = 3
Check.
(5*3 - 3)/4 + 6 = 3*3
(15 - 3)/4 + 6 = 9
12/4 + 6 = 9
3 + 6 = 9
9 = 9
Answer:
some statements that are true are :
Step-by-step explanation:
it has only 1 line of reflectional symmetry.
a line of symmetry will connect 2 vertices.
a line of symmetry will connect a vertex and a midpoint of an opposite side.
it has 7 fold symmetry.
a line of symmetry will connect the midpoints of 2 opposite sides.
For this problem your equation will be x+(x+1)+(x+2)=537
Multiply and Simplify:
x+x+1+x+2=537
3x+3=537
Subtract 3 from both sides:
3x+3-3=537-3
3x=534
Divide both sides by 3:
3x/3=537/3
x=179
179 is the middle number so: 178+179+180=537
180 is the third number.
Answer:
use symbolab
Step-by-step explanation:
3x-x=10+2
3x-1x=12
2x=12
2÷2. & 12÷2 =6
x=6
