Step-by-step explanation:

Let the number be x,

so Now

50% of x = 140

50/ 100 * x = 140

0.5x = 140

x = 140 / 0.5 

Therefore x = 280

Therefore the number is 280

Hope this helps

B is the midpoint of ac. if ab=8x-7 bc=6x+7 find ac

quester [9]

Answer: AC = 98

Step-by-step explanation:

A midpoint is a point on a line segment that divides it into two equal parts.

This means AB = BC

AB = 8x - 7

BC = 6x + 7

AB = BC

8x - 7 = 6x + 7

Solve this to find x

Add 7 to both sides

8x = 6x + 14

Subtract 6x from both sides

2x = 14

Divide both sides by 2

x = 7

Now AC = AB + BC

AC = AB + BC

AC = 8x - 7 + 6x + 7

AC = 14x

Substitute 7 for x

AC = 14(7)

AC = 98

Hope this helps!

The diagnonals of a parallelogram bisect each other ,

=》 BD = 3x × 2

=》BD = 6x

and there's given that

=》

$BD = \dfrac{3}{5} AC$

=》

$6x = \dfrac{3}{5} \times 40$

=》

$x = \dfrac{24}{6}$

=》

$x = 4$

so, if x = 4 , then the given quadrilateral is a parallelogram.

In the accompanying diagram of parallelogram ABCD, angle A =2x-10 and angle B =5x+15. Find x.

astra-53 [7]

Answer:

x = 25

Step-by-step explanation:

Mathematically, one of the properties of a parallelogram is that consecutive angles of a parallelogram are supplementary

What this means is that they add up to be 180

A and B are supplementary, and this means that their addition equals 180

Thus, adding A and B equals 180

2x -10 + 5x + 15 = 180

7x + 5= 180

7x = 180-5

7x = 175

x = 175/7

x = 25
