Answer:
- ∠ABE = 60°
- ∠DBE = 40°
- ∠FBA = 47°
- y = 2
Step-by-step explanation:
The various markings tell you that ...
GH = GI
5x -10 = 3x
2x = 10
x = 5
and
∠ABD ≅ ∠DBC
10y° = (8y+4)°
2y = 4
y = 2
The markings on GH and GI tell you that ΔGBI ≅ ΔGBH, so ...
∠CBE ≅ ∠DBC ≅ ∠ABD = 10y° = 20°
__
A) m∠ABE = 60° . . . matches choice D
__
B) m∠DBE = 40° . . . matches choice C
__
C) m∠FBA = 7(5) +6(2) = 35 +12 = 47 . . . matches choice C
__
D) The value of y is 2. . . . matches choice A
Hello,
2x+y=1
3x-y=-6
==>5x=-5
==>x=-1 and y=1-2*(-1)=3
Sol={(-1,3)}
Answer A
The simplified form of that decimal in fraction form is 3/20. Hope this helps.
9 is 18% of 50. So, 50 percent also written as 50% means 50 out of 100 parts. Since there are exactly two 50s in 100, fifty percent is the same number as one half. 50 percent=0.5 in but as a fraction, its 1/2.
Answer:
1/6
Step-by-step explanation:
As the purple die has already rolled and the number landed is 6, to find the probability of the sum of the dice being 7, there is only one option for the yellow die:
purple result + yellow result = 7
6 + yellow result = 7
yellow result = 1
So the yellow die needs to roll a 1, over a total of 6 possibilities, so the probability is 1/6
