A square has an area of 20 square feet. What is the length of a side of the square, in feet?

Irma has a total point of -8 now.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given that, Irma is just learning to play the Happy Fairies video game.

In the game, based on the taking care of fairies, players gain and lose points.

Initial point Irma had = -5 points

Fairy fell over in the wind and she got -3 points.

Final point = -5 + -3

                 = -5 - 3

                 = -8

Hence the total points now is -8.

Answer:

x° = 58.5°

Step-by-step explanation:

90° + 31,5° + x° = 180°

121.5° + x° = 180°

x° = 180° - 121.5°

x° = 58.5°

Answer:  SLOPE=-170, Y-INTERCEPT = 1020

Step-by-step explanation:

Calculate the slope:  Take any two points and find the changes in x and y:

I'll use (4, 340) and (6, 0):

Change in y (the rise) is (0 - 340) = -340.

The change in x is (6-4) = 2

The slope is the rise (y) over the run (x):  -340/2 or -170.

The y-intercept is the value of y when x=0.  The f=-data provided has a value for y at x=0:  (0,1020).  So the interecpt is 1020.

Step-by-step explanation:

yes, in a similar way as division is a shortcut for repeated subtraction.

you do know, that you normally have to add the points win in a game, right ?

so, your score grows by 200 points each time you score.

that means

200

200

200

...

200

what do you think you do to get the total ? you add all the points.

you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.

but you did not have 200 hits, you only got 12 hits.

so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).

and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.

that is how multiplication works and helps with additions.

Answer:

256 ways

Step-by-step explanation:

Okay so n cannot be in the nth place, but there are 5 places available.

So thinking about it technically you can have 4 of each number in a different spot not their own, and 4x4x4x4 = 256

However, if that doesn't work, you could try 4! which is 4x3x2x1 = 24

Answer:

(-1, 7)

Step-by-step explanation:

Step 1 - Make the two equations equal the same:

3x + y = 4

2x + y = 5

Add 1 to the first equation:

3x + y + 1 = 5

2x + y = 5

3x + y + 1 = 2x + y

Step 2 - Subtract 2x from both sides to isolate y:

3x + y + 1 = 2x + y

3x - 2x + y + 1 = 2x - 2x + y

x + y + 1 = y

Step 3 - Subtract y from both sides:

x + y + 1 = y

x + y - y + 1 = y - y

x + 1 = 0

x = -1

Step 4 - Plug known variable back into the first equation:

3x + y = 4

3(-1) + y = 4

-3 + y = 4

Step 5 - Add 3 to both sides to isolate the y:

-3 + y = 4

-3 + 3 + y = 4 + 3

y = 7

Meaning the two coordinates  are:

x = -1

y = 7

Or:

(-1, 7)
