I know the answer to 255.5 ➗ 7 but how would you write it out.. (I'm not smart)
Ainat [17]
There are several ways such as
255\frac{1}{2} / 7

First put it in the decimal equation
Since there is a decimal in the number being divided(255.5), you move the decimal so that it is a whole number(2555) but since you move the decimal place once, you do the same to the 7 so that it is now 70. So now it's 2555/70 which looks like 365 but then, you have to place the decimal value so that it is now 36.5
This is what you use to divide as shown.

What is the result of substituting for yin the bottom equation? y=x+3 y= x^2 + 2x - 4​
marta [7]

Answer:

  x +3 = x^2 +2x -4

Step-by-step explanation:

Straight substitution of the top expression for y gives you ...

  x +3 = x^2 +2x -4

__

This lets you rewrite the equation to standard form as ...

  x^2 +x -7 = 0

and find the solutions to be ...

  x = (-1±√29)/2

Corresponding y-values will be 3 more than this:

  y = (5±√29)/2

What is the approximate value of R in the equation below?<br> (76.4)(.32)(R-112)+(.35)(20R+435)=54
givi [52]
(76.4)(0.32)(R - 112) + (0.35)(20R + 435) = 54
24.448(R - 112) + 7R + 152.25 = 54
24.448R - 2738.176 + 7R + 152.25 = 54
31.448R - 2585.926 = 54
31.448R = 54 + 2585.926
31.448R = 2639.926
R = 2639.926/31.448
R = 83.9457
