I NEED THIS ANSWER QUICK (5 1/6 - x) ∙ 2.7 - 5 3/4 = -1.25 what is x
fgiga [73]

Answer:

  x = 3 1/2

Step-by-step explanation:

You could simplify the given equation first, then solve the resulting 2-step linear equation. It might work better to undo the operations done to the variable.

<h3>Solution</h3>

  (5 1/6 -x)(2.7) -5 3/4 = -1 1/4 . . . . . given

  (5 1/6) -x)(2.7) = 4 1/2 . . . . . . . add 5 3/4 to both sides

  (5 1/6 -x) = 4.5/2.7 = 5/3 . . . divide by 2.7

  31/6 -10/6 = x . . . . . . . . . . add x-5/3, use common denominators

  21/6 = x = 7/2

  x = 3 1/2

Describe the error(s) that occurred and show the correct solution.
RideAnS [48]

Answer:

-x^{2}+4x

Step-by-step explanation:

we have

(x^{2}+x)-(2x^{2} -3x)

step 1

Eliminate the parenthesis

x^{2}+x-2x^{2} +3x

The symbol of the term 3x is incorrect, must be positive instead of negative

so

-(-3x)=+3x

Group terms that contain the same variable

(x^{2}-2x^{2})+(x+3x)

Combine like terms

-x^{2}+4x
