Answer:

1st evening: 23

2nd evening: 36

3rd evening: 18

Step-by-step explanation:

Total: 77

2nd: 2 * 3rd evening

1st: 3rd evening + 5

Let x represent the 3rd evening.

77=(2*x)+(x+5)+x

x=18

What numbers multiply to equal -9 but add up to 12?
Elan Coil [88]
I don't think this is possible.

The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3

And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0

Sorry but there is not an answer. :(

So the length is 4*28=112mm
The width would be calculated like this:

you draw an equilateral triangle in the middle with sides or 2r(56mm). The based on pythagorean theorem u know that
h=rad(56^2-28^2)=48.497
28+28+h=104.497

The area would be S=l*w which is 11703.7113mm

Write greatest unit fractions that are repeating decimals. Then express each fraction as a decimal.
LekaFEV [45]
Our repeating decimal would be= 0.5555….
Let’s give 0.5555….. repeating decimal a variable of x:
x= 0.5555…. or 0.5(move 1 point to the right)
So ,10x = 5.5555 or 5.5

Now, Let’s do subtraction:
10x = 5.5555… or 5.5  
<u>-   x =  0.5555… or 0.5</u>
 9x  = 5.0            or 5.0

To get a fraction, provide a denominator the same with the numerator of variable x which is 9. Then divide the difference:
<span><u>9x</u> = <u>5.0</u>  
9        9</span> <span> <span><span> <span> <span>Therefore, x = <u>5
</u>                                     9</span> </span> </span> </span></span>
