Answer:

x = 8/3

y = 7/3

Step-by-step explanation:

In a parallelogram the diagonals bisect each other.

So 2x = y + 3

x + y = 5

Then you set them up to do combination/elimination to solve for the two variables.

2x-y = 3

Then you add the two equations together

3x = 8

Solve for x

x = 8/3

Then solve for y by plugging it into a equation

x + y = 5

8/3 + y = 5

8/3 - 5 = -y

8/3 - 15/3 = -y

-7/3 = -y

y = 7/3

Answer:

Part A: 3,

Part B: - 4

Step-by-step explanation:

~ Part A ~

The problem would be in terms of such an expression: ( - 6 - ( - 3 )^2 )/ -5

Now knowing the expression, let us simplify in terms of basic algebra:

( -6 - 9 )/ -5 = ( - 15/ - 5 ) = Answer; 3

~ Part B ~

We know the problem to be p^2/ r, but we must substitute the value of p being -10, and r ⇒ -25: ( - 10 )^2/ -25

Now let us simplify the expressions:

( - 10 )^2/ -25 = 100/ - 25 = Answer; -4

Answer: 3.51%

Step-by-step explanation:

Percent error is theoretical minus experimental, divided by the theoretical, and multiplied by 100.

$error=(\frac{(T-E)}{T} )*100$

$error=(\frac{(17.1-16.5)}{17.1} )*100$

= 3.51%
