<span>A </span>regular triangle<span> is one for which all </span>sides<span> are </span>congruent<span> and all </span>interior angles<span> are congruent, the sum of the interior angles are always 180°, so 180 : 3 = 60°
60°</span>
Answer:
Yes I believe so is that algebra i think you set up the equation correctly I'm in a college statistic class our equations that we work with much more similar to algebra.
Step-by-step explanation:
Answer: the service charge per hour for premium services is $5.5
the service charge per hour for regular services is $3
Step-by-step explanation:
Let x represent the service charge per hour for premium services.
Let y represent the service charge per hour for regular services.
One customer was charged $38 after spending 2 h in premium areas and 9 regular hours. It means that
2x + 9y = 38- - - - - - - - - - - 1
Another customer spent 3 h in premium areas and 6 regular hours and was charged $34.50. It means that
3x + 6y = 34.5- - - - - - - - - - -2
We would eliminate x by multiplying equation 1 by 3 and equation 2 by 2. It becomes
6x + 27y = 114
6x + 12y = 69
Subtracting, it becomes
15y = 45
y = 45/15
y = 3
Substituting y = 3 into equation 1, it becomes
2x + 9 × 3 = 38
2x + 27 = 38
2x = 38 - 27 = 11
x = 11/2 = 5.5

Answer:
width = 20
length = 28
Step-by-step explanation:
perimeter=96
width=x
length=x+8
(length*2) + (width*2) = perimeter
2(x+8) + 2(x) = 96
2x+16+2x=96
4x+16=96
4x=80
x=20
width = 20
length = 28
