For what value of x must ABCD be a parallelogram?<br><br> Picture below*
sesenic [268]

Answer:

x = 5

Step-by-step explanation:

Comment

BD is already given to you as bisected. AC must also be bisected. That means that 6x and 7x - 5 must the the same value. Then and only then will the figure be a parallelogram. (a four sided figure is a parallelogram if the 2 diagonals are bisected.

Equation

6x = 7x - 5                    Subtract 6x from both sides

Solution

6x - 6x = 7x - 6x - 5     Simplify

0 = x - 5                        Add 5 to both sides

5 = x - 5 + 5                 Simplify

x = 5

How does 0.03 compare to 0.003
kati45 [8]

0.03 compare to 0.003

While comparing decimals we write the decimals one below the other according to the place value of each digits in place value chart

ones -- point -- Tenths -- Hundredths -- Thousandths

 0          .             0              3

 0          .             0              0                      3

Now we compare each digit left to right. We have 3 in hundredths  and 0 in hundredths place. 3 is greater

So 0.03  is greater than  0.003

0.03 > 0.003

A cube with sides numbered 1 to 6 is rolled 300 times. What is the best prediction for the number of times that a 1 or 2 would b
Leno4ka [110]
The answer is A.

Divide 300 by the number of faces of a cube.

Since there are 6 faces on a cube then we divide it.

300 ÷ 6 = 50.

So exactly 50 times.

Hope this helps :)
