Answer:

Yes

Step-by-step explanation:

0.23 = 23/100.

AS a rational number is defined as a number which can be written as a/b , where a and b are integers, in its simplest form then we can definitely say that 0.23 is rational.

Answer:

  8 = 3x - 4y

or  y = (3/4)x - 2

Step-by-step explanation:

(4,1)  and (0, -2)  are the two points I see.

slope =  (1 -(-2))/(4 - 0) =  3/4

y-int:  -2

y = (3/4)x - 2

or   2 =  (3/4)x - y

  8 = 3x - 4y

Need help with the question at the top<br><br> Thanks
Effectus [21]

First we must find area of a single square.

Meaning we divide total area of 80 centimetres squared by 5 since we have 5 squares in the shape.

A_{square}=\frac{A_{shape}}{5}=\underline{16}

Now from the picture we can see that the perimeter of shape is combined by 4 times 3 times the length of side of 1 square.

So we need to find side of 1 square.

a=\sqrt{A_{square}}=\sqrt{16}=\underline{4}

As we stated before the formula for perimeter of this shape is:

P=4(3\cdot a)=4(3\cdot4)=4\cdot12=\boxed{48}

The perimeter of shape is 48 centimetres.

Hope this helps.

I'm lowkey bout to have a heart attack if I don't get a tutor :(
allochka39001 [22]

Answer:

5(2x + 6) = -4(-5 -2x) + 3x

10x + 30 = 20 + 8x + 3x

10x + 30 = 20 + 11x

Applying the additive inverse property, we get,

10x + 30 - 10x - 20 = 20 + 11x - 10x - 20

10 = x
