Answer:
AC = 46BD = 50Step-by-step explanation:
The property of diagonals of a parallelogram:
diagonals bisect each otherDiagonal ACAC = 2(3y - 1)AC = 2(y + 15)Compare and solve for y:
3y - 1 = y + 153y - y = 15 + 12y = 16y = 8AC = 2(3*8 - 1) = 46Diagonal BDBD = 2(5x)BD = 2(3x + 10)Compare and solve for x:
5x = 3x + 102x = 10x = 5BD = 2*5*5 = 50The answer is:
AC = 46BD = 50Correct choice is A
Jin ye only has to answer 30% of her math packet if there are only 70 questions in the packet, how many questions must she answer
Answer: She must answer 21 questions.
Step-by-step explanation:
GIven: Percent of question she need to answer = 30%
i.e. Total questions she must answer = 30% of (Total questions in the packet)
Since there are 70 questions in the packet, then the number of question she must answer will be
30% of 70
= 0.30 x 70 [30%=0.30]
= 21
Hence, she must answer 21 questions.

So here you’ve got 4 options
A)2 x 2/5
B)1 x 1/5
C)8 x 1/5
D)6 x 2/5
Simplifying the question:
4x2/5= 4x0.4 = 1.6

2x 2/5= 2x0.4= 0.8
Solving option B:
1x1/5 = 1x0.2 = 0.2
Solving option C:
8x1/5 = 8x0.2= 1.6
Solving option D:
6x 2/5 =6x 0.4=2.4
Hence option C: 8x1/5 is the correct answer
