Midsegment = 1/2(base1 + base2)
EF = 1/2(AB + CD)
EF = 1/2(20 + 12)
EF = 1/2(32)
EF = 16
Answer
EF = 16
Answer: x= -23/2
Step-by-step explanation:
multiply both sides of the equation by 6
x-5=3(x+6)
distribute 3
x-5=3x+18
move variables to lest-hand side and change sign
x-3x=18+5
like terms
-2x=23
the divide both sides by -2
x= -23/2
Answer:
27/2 in^3 or 13.5 in^3 as a mixed fraction
Step-by-step explanation:
V=whl
Simplify the following:
(1 + 1/2) (2 + 1/4)×4
Put 1 + 1/2 over the common denominator 2. 1 + 1/2 = 2/2 + 1/2:
(2/2 + 1/2) (2 + 1/4)×4
2/2 + 1/2 = (2 + 1)/2:
((2 + 1)/2) (2 + 1/4)×4
2 + 1 = 3:
3/2 (2 + 1/4)×4
Put 2 + 1/4 over the common denominator 4. 2 + 1/4 = (4×2)/4 + 1/4:
(3×4)/2 ((4×2)/4 + 1/4)
4×2 = 8:
(3 (8/4 + 1/4)×4)/2
8/4 + 1/4 = (8 + 1)/4:
(3×4)/2 ((8 + 1)/4)
8 + 1 = 9:
3/2×9/4×4
3/2×9/4×4 = (3×9×4)/(2×4):
(3×9×4)/(2×4)
(3×9×4)/(2×4) = 4/4×(3×9)/2 = (3×9)/2:
(3×9)/2
3×9 = 27:
Answer: 27/2 or 13.5 as a mixed fraction
Step-by-step explanation:
According to rules of Proportionality :
(A) When (a = 10, b = 8, c = 2)
K = 5
(B) When (b = 20, c = 5)
