So we know nothing about blank so we can infer that’s our X in this case

So 4/5x=2/5 do inverse multiplication for 4/5 to get rid of it from the left side so you’re left with

X=5/4*2/5 just multiply across and you get 10/20 now simplify

1/2

Answer:

1/2

Step-by-step explanation:

Better write, "If (4/5)x = 2/5, what is x?  Please do not use 'x' to denote multiplication; use " * " instead.

If (4/5)x = 2/5, multiplying both sides by (5/4) will isolate x:

(5/4)(4/5)x = (5/4)(2/5), or

               x = 10/20, or x = 1/2.  The unknown number is 1/2.

I need help on writing fractions into simplest form
mojhsa [17]
Hi!

Is there a specific question you need help with? Writing fractions into simplest form is very easy. All you have to do is find a number that both the numerator and denominator can be divided by, and divide them both with it.

For example: 15/20. They both can be divided by 5. So do that. 15 divided by 5 = 3. 20 divided by 5 = 4. So the new fraction will be 3/4. It cannot be divided by another whole number. So that is the simplest form.

Pls let me know if you need more help.

Have a great day!

On a coordinate plane, a dashed straight line has a negative slope and goes through (0, 3) and (2, negative 1). Everything to th
Nimfa-mama [501]

Answer:

The answer to your question is    y < -2x + 3

Step-by-step explanation:

See the graph below

Process

1.- Find the slope

   m = \frac{y2 - y1}{x2 - x1}

Substitution

   m = \frac{-1 - 3}{2 - 0}

   m = \frac{-4}{2}

   m = -2

2.- Find the equation of the line

   y - y1 = m(x - x1)

Substitution

  y - 3 = -2(x - 0)

Simplify and solve for y

  y - 3 = -2x

  y = -2x + 3

3.- Write the inequality

As the left area of the plane is shaded the inequality must be

 y < -2x + 3
