Answer:

  D(4, 1)

Step-by-step explanation:

The two diagonals have the same midpoint, so ...

  (A+C)/2 = (B+D)/2

  A+C = B+D . . . . multiply by 2

  A+C-B = D . . . . . subtract B

  D = (1, 1) + (5, 3) - (2, 3) = (1+5-2, 1+3-3)

 D = (4, 1)

Answer:

D(4 ; 1)

Step-by-step explanation:

vector(AB)=(2-1 ; 3-1) = (1 ; 2)

vector(DC)=(5-x ; 3-y)  and D(x ; y )

ABCD  parallelogram :vector(AB)=vector(DC)

you have the system : 5-x =1

                                       3-y =2

so : x=4 and y=1

D(4 ; 1)

kvv77 [185]

Answer:

<u>314 of the people attending the fun fair are people living in the neighborhood</u>

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Number of people attending the fun fair = 2,512

Fraction of people attending the fun fair that are students = 5/8

Fraction of people attending the fun fair that are parents = 1/4

Rest of the people attending the fun fair lives in the neighborhood

2. Let's calculate the number of students, parents and people living in the neighborhood

Students:

Fraction of people attending the fun fair that are students = 5/8

5/8 * 2,512 = 1,570

1,570 of the people attending the fun fair are students

Parents:

Fraction of people attending the fun fair that are parents = 1/4

1/4 * 2,512 = 628

628 of the people attending the fun fair are parents

People living in the neighborhood

2,512 - 1,570 - 628 = 314

<u>314 of the people attending the fun fair are people living in the neighborhood</u>

1.6x=1.28<br> help me solve this
bogdanovich [222]

Answer:

Step-by-step explanation:

Sure! So, we need to divide by 1.6 on each side to isolate the x.

1.6x / 1.6 is just x. We need to divide by the same on the other side too!

1.28 / 1.6 is 0.8.

So x = 0.8
