In parallelogram defg, dh = x + 1, hf = 3y, g h = 3 x − 4 , and he = 5y + 1. find the values of x and y. the diagram is not drawn to scale.

The value of x and y is 5 and 2 respectively.

Step-by-step explanation:

Since we know that "Diagonals of parallelogram bisects each other":

So, we have given that

in parallelogram DEFG,

DH = x + 1, HF = 3y, G H = 3 x − 4 , and HE = 5y + 1.

so, According to question, as shown in the figure below:

Similarly,

Using Substitution Method to solve system of equation:

From eq(1), we get

Putting the value of x in eq (2), we get

Now,, put the value of y to get the value of x:

Hence, the value of x and y is 5 and 2 respectively.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
