Answer:
AB = BC = AC = 15
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x , that is
AC = AB , so
11x - 7 = 6x + 3 ( subtract 6x from both sides )
5x - 7 = 3 ( add 7 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Then
AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus
AB = BC = AC = 15
Answer:
5 Months
Step-by-step explanation:
If you set it up as an eqation, then the equation should be:
450+40x=975-65x.
If you solve for x, you should get 5

Answer:
28.3 m
Step-by-step explanation:
diameter=9m
circumference=pi*d
3.142*9=28.3
3x+2y =6
subtract 3x from each side
2y = -3x +6
y =-3/2 x+3
the slopes are the same so the lines are parallel
