Answer:
x ≤ 1
Step-by-step explanation:
5(x+3) - 7≤13
5x+3 - 7≤ 13
5x+15-7 ≤ 13
5x+15 ≤ 13+7
5x+15 ≤ 20
5x ≤ 20-15
5x ≤ 5
x ≤ 1
(-5/8)(X) = -0.4
(-5/8)(X) = -4/10
X = (-4/10) / (-5/8)
X = (4/10) / (5/8)
X = (4/10)(8/5)
X = (2/5)(8/5)
X = 16/25
Letter D
True.....a polygon will always have the same number of angles and sides. ex: a triangle has 3 sides and 3 angles, a Pentagon has 5 sides and 5 angles, a square has 4 sides and 4 angles...etc.
Answer:
D
Step-by-step explanation:
Answer:
v = 9 because it is what would make a great answer
Step-by-step explanation:
the angles are supplementary, meaning it sums up to 180 degrees
so to find v, you have to find the total angle of v.
180- 105 equals 8v+3, or 75 equals 8v+3
subtract 75 with 3 leaving 72 equals 8v
v would equal 9
