Answer:

x = 20

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, hence

6x - 57 = 3x + 3 ( subtract 3x from both sides )

3x - 57 = 3 ( add 57 to both sides )

3x = 60 ( divide both sides by 3 )

x = 20

According to the properties of parallelograms the diagonals bisect each other. What this means is that each "half" of a diagonal is equal to each other. With this in mind you can set each half equal to each other in an equation like so...

3x + 3 = 6x - 57

Now you must combine like terms

60 = 3x

Isolate x by dividing 3 to both sides

60/3 = 3x/3

20 = x

Hope this helped!

Answer:

the number of variables that recorded is 7

Step-by-step explanation:

The computation of the number of variables that recorded is shown below:

1. Age

2. Model

3. Exterior paint color

4. Interior color

5. Engine size

6. Number of cylinders

7. Cost of 1463 used cars

Hence, the number of variables that recorded is 7

Consider two quantities u and v that are related by the expression vp=cuq, where c is a constant. the exponents p and q are not

Mazyrski [523]

Answer:

y = (q/p)x +log(c)/p

Step-by-step explanation:

$v^{p}=cu^{q}\qquad\text{original equation}\\\\p\log{(v)}=\log{(c)}+q\log{(u)}\qquad\text{take the log}\\\\py=log{(c)}+qx\qquad\text{substitute x and y}\\\\y=\dfrac{\log{(c)}+qx}{p}$
