Is -1 and 4/5 greater than -2 and 1/8

Goryan [66]

Hey there!

The correct answer is yes.

The smaller the number with a negative sign, the larger the number actually is.
So, -1 4/5 > -2 1/8

Hope this helps! :)

1. Solve the following<br> system:<br> 2x + 2y = 38<br> y = x + 3

pashok25 [27]

Answer:

y=11

x=8

Step-by-step explanation:

This is Elimination

2x+2y=38

Subtract 2x on both sides 2y=-2x+38

Then Multiply 2(y=x+3) which equals 2y=2x+6

Solve by Elimination

2y=-2x+38

2y=2x+6

add the y's and since the x's are different those cancel out, then add 38 and 6.

then you do the equation 4y=44

divide both by 4

y=11

then you do 11=x+3

subtract 3 on both sides

x=8

and there you go

I hope this is how you wanted it solved

Can someone please help ASAP!

Pick’s Theorem is used to find the areas of figures on lattices easily. The formula is:

A = (B)/2 + I - 1, where B is the number of points on the border of the shape, and I is the number of points inside the shape.

Here, there are 8 points on the outside of the shape, and there are 12 points inside the shape. So, we do:

8/2 + 12 - 1 = 4 + 12 - 1 = 15 units squared.

We can check by finding the areas of the non-shaded region and subtracting that area from the whole rectangle area of 4 * 10 = 40:

4 * 1 + (3 * 1)/2 + 1 * 9 + (3 * 1)/2 + (9 * 2)/2 = 25

40 - 25 = 15, so we’re right!

The answer is 15 units squared, or choice (B).

What is the sum of 7 2/3 plus 8 5/6 simpified

olasank [31]

7 2/3 + 8 5/6 = 7 4/6 + 8 5/6

7+8=15 4/6 + 5/6 = 1 3/6

15 3/6 simplified is 15 1/2

The design of a garden path uses stone pieces shaped as squares with side length of 15 in. Find the length (horizontal measureme

alexira [117]

I found an image that has a similar problem.

The squares were in a diamond form. There were six squares. To get the length of the path, I have to solve for the diagonal of the square.

To solve for the diagonal of the square, I have to multiply the length one side by the square root of 2.

diagonal of one square = 15 in * √2 = 21.21 in

21.21 in * 6 squares = 127.28 inches

The length of the path is 127 inches.
