Which of the following stanements shows the inverse property of addition?1 y=y
Oy+y= 2 y
Oy+ (-) = 0
Oy+ 0 = y

Answers

Answer:

0\cdot \:y+\left(-0\cdot \:y\right)=0  the  statement shows the inverse property of addition as the sum of a number and its inverse is zero.

Step-by-step explanation:

As we know that Inverse Property of Addition states if you add any number to its opposite, the result will be zero.

For example, 13 + (-13) = 0 shows that -13 is the additive inverse of 13.

In other words, the sum of a number and its inverse is zero.

Now checking from the available options,

0y+\left(-0y\right)

\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a

=0\cdot \:y-0\cdot \:y

\mathrm{Add\:similar\:elements:}\:0\cdot \:y-0\cdot \:y=0

=0

Thus,

0\cdot \:y+\left(-0\cdot \:y\right)=0

Therefore, 0\cdot \:y+\left(-0\cdot \:y\right)=0  the  statement shows the inverse property of addition as the sum of a number and its inverse is zero.

Please help me i dont know what the answer is ??

To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
(180)/(3) = 60
Therefore, the measure of the triangle's angle is 60°

Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.

Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
90=x+60+12 \n 90=x+72 \n 90-72=(x+72)-72 \n 18=x

The missing angle measure, angle x, equals 18°.

Hope this helps!

49 is 70 of what number is sopost to be here

Answers

the answer is 70% if your trying to find the percentage if your trying to fing the of it will be 70 also
70% of a number is 49
70%    ×      n      =   49
70% = (70)/(100) = 0.7
0.7 × n = 49
Divide by 0.7 on either sides to isolate n
(0.7n)/(0.7) = (49)/(0.7)
0.7 and 0.7 cancels out
n = 70

49 is 70% of 70

Why do some equations have the same variable on both sides?

Answers

some equations have the same variable on both sides because you are supposed to solve for that number.  for example 5x+4=11-2x for this example, so you dont have to deal with negatives, you would add 2x to both sides first.  and you would do that so that  you can cancel out the variable on the right side so that it is only on the left side so you end up with, 7x+4=11.  the next thing you would do is subtract 4 from both sides so that you can get the variable by itself on one side so it would look like this, 7x=7.  and to finish it off, you would divide both sides by 7, and get x.
