Name the property that the equation illustrates. Explain. –0.3 + 0.3 = 0 A. Identity Property of Addition; 0 is part of the equation. B. Inverse Property of Multiplication; a number and its inverse are multiplied. C. Inverse Property of Addition; a number and its inverse are added.

Answers

Answer 1

Answer:

Answer is choice C) Inverse property of addition; a number and its inverse are added

The number is 0.3 and its additive inverse is -0.3, which add to 0. You can flip things around to say that the number is -0.3 and its additive inverse is 0.3 to add them to the same result of 0. The order of addition doesn't matter. It's like saying 2+3 = 5 and 3+2 = 5

Hi there!

This gets pretty easy once you understand how to do these kinds of problems. Let's look at the words in the question.

Adison earned 25$. We can push that to the side.
She loaned her friend 18$, which means she took some money away from her first part of it.

25 - 18 = 7$. Now she has 7$ left. (A calculator would be useful to answer these!)

Now, let's put the 7 to the side and check out the rest of the equation. Looks like Adison's grandmother gave her 50 more dollars, and we know that more means to add.

50 + 7 = 57$.

Now, the final part of the question says she ended up with 86$ because she had money before she earned more. To see how much money she had originally, we can subtract 86 from 57.

86 - 57 = 29$.

We now understand that Adison originally had 29$ before earning anymore money.

Hope this helps!

The endpoints of cd are C (-4,10) and D (-4,10) the coordinates of the midpoint M of CD are

Answers

The endpoints C and D has nomidpoint M.

Step-by-step explanation:

step 1: The given endpoints of C and D are (-4,10) and (-4,10)

step 2: Midpoint formula = ((x1+x2)/2 , (y1+y2)/2)

step 3: Here, C(-4,10) = (x1,y1)

D(-4,10) = (x2,y2)

step 4: The midpoint represents the half distance of the line CD. Since C and D are same points, they cannot form a line. Therefore, the endpoints CD have no midpoint.

Sarah gave the same answer when asked to round 4 7/8 to the nearest inch and half a inch. Explain why Sarah is correct.

Answers

when you take 4 7/8 and round it up to the next inch u round up because 7/8 is bigger than 1/2 so thats 5
u would round it up to 5 again for the nearest half inch because 7/8 is closer to 1 than 1/2 which brings it to 5
