Option B. From the parallelogram PQRS the value of y is given to be 30

<h3>How to solve for the value of y from the parallelogram</h3>

In order to get the value of y we have to use the formula

2y + 120 = 80

where the value 120 is the angle that is stated as 120 from the question

2y = 180 - 120

2y = 60

y = 60 / 2

y = 30

Hence the value of y = 30

We can go ahead to get the value of x as well

3x + 120 = 180

take the like terms

3x = 180 - 120

3x = 60

divide through by 3 to get x

60 / 3 = x

20 = x

A page was missing from a 72 - page book. When Josh added up the remaining page numbers, the sum was 2521. Which page was missin
morpeh [17]
The numbers 1 to 72 add up to (1+72) x 72/2 = 73 x 36 = 2628
If we take away what Josh got we have 2628 - 2521 = 107
Pages in a book are odd on the first side and even on the second, so pages 11 and 12 are on the same sheet.
107 / 2 = 53.5 so the missing page had 53 on one side and 54 on the other side.
The remaining pages would have been numbered 1, 2, 3, ..., 51, 52, 55, 56, ... 71, 72

Which tables display linear functions?Check all that apply<br><br> Please help me!!!!!
zhuklara [117]

Answer:

The first one and the last one.  A and D.

Step-by-step explanation:

A linear equation is and equation where the line is going up on a graph.  In order for that to happen, y must always be bigger than x.  The first and last chart all the way to the right is the only one that has that trait.  :)

Please help!! <br><br> Evaluate the determinant of the matrix.
kicyunya [14]

i can not give the answer unless you still cannot find it after these steps but I have steps that might help

1. Set the matrix (must be square).

2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.

3. Multiply the main diagonal elements of the matrix - determinant is calculated.

Hi!

You can always add or subtract same value to/from both sides of equation. The same is true about multiplication and division.

In your case you have to subtract x from both sides of equation in order to get rid of it on the left side:
x+2y-x=8-x
2y=8-x

But it's easier to remember that if you want to move some member of equation to other side, you just have to change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):
+x+2y=+8

Move 2y to the right side:
+x=+8-2y

Move 8 to the left side:
+x+2y-8=0

Move both x and 2y to the right side:
0=8-x-2y
