Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E. If AD=4w-5,DE=4,BE=x/2, and BC-7w-17, solve for x.

Answers

Answer 1

Answer: Given:
Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E.
AD = 4w - 5
DE = 4
BE = x/2
BC = 7w - 17

AD and BC are parallelogram, this means that they are equal in measure.

AD = BC
4w - 5 = 7w - 17
4w - 7w = -17 + 5
-3w = -12
w = -12/-3
w = 4

AD = BC
4(4) - 5 = 7(4) - 17
16 - 5 = 28 - 17
11 = 11

DE = BE
4 = x/2
4*2 = x
8 = x

The value of x is 8.

Answer 2

Answer:

Answer: The value of x is 8.

Correct option d)0.61

Step-by-step explanation:

Here we have a number line from 0 to 1 . With every point at a equal distance of 0.10 from each other . Let's first mark the decimal 0.74 in number line . Now, Lets check one by one that which decimal is less than 0.74 . Remember , decimal will be less than 0.74 if point lies to the left side of 0.74.

a)0.95:

Decimal 0.95 lies to right side of 0.74 , So this decimal is not smaller than 0.74

b)0.88:

Decimal 0.88 lies to right side of 0.74 , So this decimal is not smaller than 0.74

c)0.79:

Decimal 0.79 lies to right side of 0.74 , So this decimal is not smaller than 0.74

d)0.61:

Decimal 0.61 lies to left side of 0.74 , So this decimal is smaller than 0.74

Explain how you could add 678 + 303 using mental math

Answers

678 + 303 = 981

Here are a few examples to get you started:
600 + 300 = 900
78 + 3 = 81
900 + 81 = 981
Here's another one:
678 = 600 + 70 + 8
303 = 300 + 00 + 3
Add the ones place = 11
Add the tens place = 70
Add the hundreds place = 900
Now add 900 + 70 + 11 = 981
Hope this helps! :-)
